Abstract
Description
Automatisch die Tuchspannung ausgleichende aufrollbare Bedachungsinstallation Automatically the fabric tension compensating roll-up roofing installation
Die Erfindung betrifft eine aufrollbare Bedachungsinstallation, umfassend zumindest eine Wickelweile und ein stoffartiges Bedachungselement, welche wand- oder deckenseitig zur Montage vorgesehen ist. The invention relates to a roll-up roofing installation, comprising at least one Wicking and a fabric-like roofing element, which is provided on the wall or ceiling side for mounting.
Bei diesen aufrollbaren Bedachungselementen, insbesondere bei Markisen und Sonnensegein entstehen beim Vorgang des Aulwickeins auf die Welle häufig ungleiche Spannungsverteilungen. Diese entstehen zum Beispiel durch Ungenauigkeiten beim Nähen oder konstruktionsbedingt durch den beim Aufwickeln des Tuches entstehenden größeren Wickelradius an bestimmten Stellen, wie zum Beispiel mehrlagig vernähter Tuchbereiche, wie die Kanten oder Verbindungsnähte oder auch durch spezifisch konstruktionsbedingt eingebrachte und dadurch partiell zusätzliche das aufzuwickelnde Volumen erhöhende Bauteile im Tuch, wie zum Beispiel besondere Verstärkungen und Verbindungsteile bei Lattentaschen und in die Tuchfläche eingebrachten Querprofilen und Segellatten. In these roll-up roofing elements, especially in awnings and Sonnensegein arise in the process of Aulwickeins on the shaft often uneven voltage distributions. These arise, for example, due to inaccuracies in sewing or due to the design caused by the winding of the cloth larger winding radius at certain points, such as multi-layer sewn cloth areas, such as the edges or seams or by specifically design-related and thus partially additional volume to be wound up increasing components in the cloth, such as special reinforcements and connecting parts in batten pockets and introduced into the cloth surface cross sections and battens.
Diese sich beim Aufwickeln solcher dickerer Teile der Tuchflächen entstehende ungleiche Spannungsverteilung im Rest des noch aufzuwickelnden Tuches sorgen beim fortgesetzten Aufwickeln des Tuches häufig für eine Faltenbildung des dann ungleich zur Welle gespannten Tuches. insbesondere bei Installationen wie Sonnensegeln mit teilweise bis zu 8 m und größer aufzuwickelnden Tuchbahnen ist bekannt, dass zum Beispiel die Umnähte der Kanten, sowie auch die Verbindungs- und Überlappungsnähte nicht im 90 Grad Winkel zur Wickelwelle stehen sollten. Sobald diese im 90 Grad Winkel zur Welle liegen, bilden sich schon nach wenigen Umwicklungen des Aufwickefvorgangs deutlich höhere Wickelradien an diesen mehrlagig ausgestatteten Tuchbereichen aus. Dadurch konzentriert sich die vom freien Zugende des Segels kommende und zuvor im ausgewickelten Zustand relativ gleichmäßig im Tuch verteilte Zugspannung mit zunehmendem Wickelradius immer mehr auf diese Bereiche. Im Falle von umnähten Kanten, die im 90 Grad Winkel zur Welle stehen, bedeutet dieses, dass zuletzt beim Aufwickein des Segeis, der auf der Welle aufgebaute Wickelradius im Bereich der Kanten so groß ist, dass der größte Teil der eigentlich zuvor auf die gesamte Breite des aufzuwickelnden Tuches verteilten Zugkraft nun auf den umsäumten Kantenbereichen des Segels liegt. This uneven distribution of tension in the remainder of the still-to-be-wound cloth resulting from the winding-up of such thicker parts of the cloth surfaces frequently causes wrinkling of the cloth, which is then unequal to the shaft, during continued winding of the cloth. especially in installations such as sun sails with partially up to 8 m and larger wound fabric webs is known that, for example, the seaming of the edges, as well as the connecting and overlapping seams should not be in the 90 degree angle to the winding shaft. As soon as they are at 90 degrees to the shaft, significantly higher winding radii are formed on these multi-layered cloth areas after just a few wrappings of the winding process. As a result, the tension coming from the free end of the sail and previously distributed relatively evenly in the unwrapped state in the cloth concentrates with increasing winding radius more and more on these areas. In the case of seamed edges that are at 90 degrees to the shaft, this means that last when winding up the sea ice, the winding radius built up on the shaft in the area of the edges is so large that most of the previously on the entire width of the cloth to be wound distributed tensile force is now on the edge of the sail edges umsäumten.
Dieses führt neben dem Problem einer ungleichen Wickelspannung der Tuchfläche und dem damit einhergehenden Effekt eines unschön fältig aufgewickeltem Segeis vor allem auch zu einer dauerhaften Tuchveränderungen in diesen überspannungsbelasteten Teilbereichen der aufgewickelten Tuchbahnen. Durch die vergleichsweise sehr hohen Spannungskräfte in diesen Teilbereichen des Tuches entstehen dort partiell sogenannte Überdehnungswellen im Tuch, die sich nicht mehr zurückbilden können, weil das Tuch dort beim Aufwickeln über seine Elastizitätsgrenze hinaus gespannt wurde. This leads, in addition to the problem of unequal winding tension of the cloth surface and the associated effect of a bleak wound wound seaweed especially to a permanent cloth changes in these overstressed portions of the wound fabric webs. Due to the comparatively very high tension forces in these subregions of the cloth, partial so-called overstretching waves in the cloth, which can no longer be formed, arise because the cloth was stretched beyond its elastic limit during winding.
Insbesondere spezielle Konstruktionen von Bedachungselementen mit ungleichen Materiafstärken und ungleichen aufzuwickelnden Stofflängen wie zum Beispiel aus DE202015002127 U1 bekannt sind nur schwer falten- und verzugsfrei aufzuwickeln, oder sind mit heutigem Stand der Technik kaum ais aufwickelbare Konstruktion zu realisieren. In particular, special constructions of roofing elements with unequal material strengths and unequal material lengths to be wound, such as those known from DE202015002127 U1, are difficult to wind without folding and distortion, or can hardly be realized as a windable construction with the current state of the art.
Im Stand der Technik finden sich zu diesem Problem keine beziehungsweise nur Hinweise auf Umgehungslösungen des Problems. Im Bereich der Markisen werden von den Branchenvertretern diese Wellenbildungen auf Grund des erhöhten Wickelradius und der damit dort erhöhten Tuchspannungen beim Aufwickeln ais technisch gegeben angesehen, aber nicht als die Eigenschaft des Tuches mindernde Eigenschaft beschrieben. Insbesondere im Bereich der Sonnensegel richten sich die Art der Segelgrundrisse und der Zuschnitte nach der bestmöglichen Verhinderung dieser partiellen Zunahme des Wickelradius durch Grundrisse die möglichst keine oder nur kleine aufgedoppelte Naht- und Kantenbereiche in einem 90 Grad Winkel zur In the prior art, there are no or only hints on circumvention solutions of the problem to this problem. In the field of awnings are considered by the industry representatives wave formations due to the increased winding radius and thus increased fabric tension during winding ais given as technical, but not described as the property of the cloth-reducing property. In particular, in the field of sun sails, the type of sail floor plans and blanks to the best possible prevention of this partial increase of the winding radius by floor plans the possible no or only small doubled seam and edge areas in a 90 degree angle
Wickelwelie aufweisen. So werden rechteckige Grundrisse meist nie ganz rechteckig, sondern meist leicht trapezförmig konstruiert, so dass sich die umnähten Kanten des Tuches beim Aufwickeln nebeneinander und nicht übereinander legen. Ein anderes Verfahren zur Verhinderung der partiellen Zunahme von Wickelradien auf der Welle, wie zum Beispiel von Nähten im Bereich der inneren Tuchfläche ist die als Sternschnitt bekannte sternförmige beziehungsweise leicht schräg zur Wickelwelle angeordnete Verlaufsrichtung von Verbindungsnähten. Have Wickelwelie. For example, rectangular floor plans are usually never completely rectangular, but are usually slightly trapezoidal in design, so that the seamed edges of the Towel when winding next to each other and not on top of each other. Another method for preventing the partial increase of winding radii on the shaft, such as seams in the region of the inner fabric surface is known as a star-shaped star-shaped or slightly inclined to the winding shaft extending direction of connecting seams.
Oer vorliegenden Erfindung liegt die Aufgabe zu Grunde, ungleiche Spannungsmomen* te im Tuch beim Aufwickeln auf die Wickelwelle automatisch auszugleichen, sowie auch die, durch das Aufwickeln einer Tuchfläche mit unterschiedlicher Materialstärken innerhalb dieser Fläche entstehenden unterschiedlichen Wickelradien auf der The present invention is based on the object, automatically compensate for unequal Spannungsmomen * te in the cloth when winding on the winding shaft, as well as, by winding a cloth surface with different thicknesses of material within this area resulting different winding radii on the
Wickelwelle automatisch auszugleichen und damit eine möglichst immer gleichbleibende Tuchspannung und einen gleichbleibenden Wickeldruck zwischen der Wickelweile und der aufzuwickelnden Tuchfläche entlang der Wickelwelle zu erreichen. Automatically compensate winding shaft and thus to achieve as constant as possible fabric tension and a consistent winding pressure between the winding time and the wound-up cloth surface along the winding shaft.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Wickelwelle und/oder das aufzuwickelnde Bedachungselement ein dauerelastisches Volumenelement aufweist. Weitere vorteilhafte Ausgestaltungen sind den Unteransprüchen zu entnehmen. According to the invention, this object is achieved in that the winding shaft and / or the roofing element to be wound up has a permanently elastic volume element. Further advantageous embodiments can be found in the dependent claims.
Die Erfindung betrifft eine aufrollbare Bedachungsinstallation, die sich während des Aufwickeins des Sedachungselementes häufig entlang der Wickelwelle ergebende ungleiche Veränderung des Wickelradius und/oder der Tuchspannung und/oder des Wickeldruckes zwischen der Welle und dem Bedachungseiement automatisch ausgleicht. The invention relates to a roll-up roof installation which automatically compensates for uneven change in the winding radius and / or the fabric tension and / or the winding pressure between the shaft and the roofing element during the winding of the sedimentation element along the winding shaft.
Hierzu schlägt die Erfindung im Wesentlichen vor, dass die Wickelwelle und/oder das aufzuwickelnde Bedachungselement ein zusätzliches dauerelastisches Volumenelement erhält, dass den Wickelradius auf der gesamten Breite der Wicklung parallel zur Welle in etwa gleichmäßig erhöht. Es kann sich sowohl direkt auf oder an der Welle befinden als auch integrierter Bestandteil der Wickelwelle sein. Es kann sich aber auch als Bestandteil des aufzuwickelnden Bedachungselementes in diesem integriert sein, so zum Beispiel in einer Art länglichen Tasche parallel zur Wickelwelle, wie in einer Segeilattentasche. Das dauerelastische Volumenelement ist in seiner auf die Wickelwelle auftragenden Volumenstärke und in setner Elastizitätshärte so bemessen, dass es bei normaler gleichmäßiger durchschnittlicher Zugspannung der Tuchfläche der jeweiligen For this purpose, the invention essentially proposes that the winding shaft and / or the roofing element to be wound up receives an additional permanently elastic volume element which increases the winding radius approximately uniformly over the entire width of the winding parallel to the shaft. It can be located either directly on or on the shaft as well as be integrated part of the winding shaft. But it can also be integrated as part of the aufzuachelnden roofing element in this, so for example in a kind of elongated bag parallel to the winding shaft, as in a Segeilattentasche. The permanently elastic volume element is dimensioned in its application to the winding shaft volume and set set elasticity so that it is normal normal average tensile stress of the fabric surface of the respective
Installation das auftragende Volumen ohne größere Einbußen beibehält und dass es bei partieller Zunahme einer partiell höheren Zugspannung in der Art elastisch nachgibt, dass sein Volumen an dieser belasteten Stelle soweit komprimiert wird, bis die Installation which maintains the application volume without major losses and that it gives way elastically with partial increase of a partially higher tensile stress in the way that its volume is compressed at this loaded point until the
Tuchspannung und/oder der Wickeldruck zwischen Tuchfläche und Welle wieder in etwa der Übrigen Tuchspannung und/oder dem übrigen durchschnittlichen Druck auf der Wickelweile entspricht. Fabric tension and / or the winding pressure between the fabric surface and the shaft again corresponds approximately to the other fabric tension and / or the remaining average pressure on the Wicking.
Weder die verwendeten Tücher noch die Wickelwellen besitzen im Stand der Technik die notwendige Elastizität, um derartig beim Aufwickein ungleicher Materialstärken innerhalb einer Bedachungsfläche entstehende ungleiche Spannungen auszugleichen. Neither the wipes nor the winding shafts used in the prior art have the necessary elasticity to compensate for uneven stresses arising during winding in unequal material thicknesses within a roofing area.
Das elastische Volumenelement kann die durch ungleiche Materialvolumen beim The elastic volume element can by the uneven material volume
Aufwickeln entstehenden möglichen Radiendifferenzen dadurch automatisch ausgleichen, indem es mitteis seiner Elastizität an jeder mit überdurchschnittlichem Druck und Spannung beanspruchten Stelle des Volumenelements in Richtung des Radienzentrums der Wickelwelle elastisch nachgibt. Winding resulting possible differences in radii thereby compensate automatically by mitteis its elasticity at each stressed with above-average pressure and stress point of the volume element in the direction of the radius center of the winding shaft elastically yielding.
In einer Ausführung der Erfindung besteht das dauerelastische Volumenelement beispielsweise aus einer in etwa vollflächig um die Wickelwelle herum aufgebrachten geschlossenzelligen Kunststoffschaumstoffschicht. In stärker beanspruchten Teilbereichen des Kunststoffschaumstoffes wird das in den Zellen befindliche Gas bei Druck soweit komprimiert, bis sich auch dort der äußere Wickelradius dem übrigen Wicketra- dius auf der Welle wieder angeglichen hat. Wird das Tuch wieder abgewickelt dehnt sich das Kunststoffelement an der zuvor komprimierten Steile wieder zu seiner ursprünglichen und gleichmäßig belasteten Form aus. in einerweiteren Ausführung der Erfindung Ist das Vdlumenelement schlauchförmig ausgeformt und besteht ebenfalls aus einer Art geschlossenzelligem Kunststoffschaumstoff ähnlich der Art eines Isolierschlauches für Heizungsrohre. In der aufwickelbaren Bedachungsfläche befinden sich hierfür in etwa parallel zur Wickelwelle eine Art Segellattentaschen in denen zusätzliche Spannelemente eingebracht sind, wie aus der Anmeldung DE 102011122502 A1 bekannt. Dieses Spannelement wird jeweils in das schlauchförmige Volumenelement eingeschoben und kann gemeinsam mit dem In one embodiment of the invention, the permanently elastic volume element consists, for example, of a closed-cell plastic foam layer applied approximately over the full area around the winding shaft. In regions of the plastic foam which are subjected to greater stress, the gas in the cells is compressed under pressure until the outer winding radius there has also matched the rest of the winding radius on the shaft. If the cloth is unwound again, the plastic element expands again at the previously compressed location to its original and evenly loaded form. In a further embodiment of the invention, the Vdlumenelement is formed tubular and also consists of a kind of closed-cell plastic foam similar to the type of insulating tube for heating pipes. In the windable Bedachungsfläche are for this purpose approximately parallel to the winding shaft a kind of canvas bags in which additional clamping elements are introduced, as known from the application DE 102011122502 A1. This clamping element is inserted in each case in the tubular volume element and can be used together with the
Volumenelement in die jeweilige Segellattentasche einfach eingeführt werden. Volume element can be easily inserted into the respective batten pocket.
Das Volumenelement kann beispielsweise auch aus einem einfachen schlauchartigen elastischen Material bestehen, welches entweder mit Gas oder sogar mit einem Liquid gefüllt ist. Alternativ kann das Volumenelement auch aus einer Art Moosgummi oder ähnlich elastischem Material bestehen. The volume element can for example also consist of a simple tube-like elastic material which is filled either with gas or even with a liquid. Alternatively, the volume element may also consist of a type of sponge rubber or similar elastic material.
Das Volumenelement kann dauerelastisch sein und sich nach jeder die Erfindung betreffenden Belastungssituation in einem Teilbereich der Aufwicklung verformen und sich beim Abwickeln des Bedachungselementes wieder zurücksteilen. The volume element can be permanently elastic and deform after each loading situation relating to the invention in a partial area of the rewinding and back again when unwinding the roofing element.
Je nach Aufgabenstellung der spezifischen Konstruktion des Bedachungselementes, reicht es aber erfindungsgemäß auch aus, wenn das Volumenelement nur einmalig bei der ersten spezifischen Belastung in dem erfindungsgemäß besonders beanspruchten Teilbereich nachgibt, ohne sich beim erneuten Abwickeln des Bedachungselementes erneut elastisch auszudehnen. Es ermöglicht dann eine einfache aber effektive individuelle Formgebung der Wickelwelle, deren Form dann den Wickelanforderungen der spezifischen Konstruktion des Bedachungselementes entspricht. Depending on the task of the specific construction of the roofing element, but it is sufficient according to the invention, if the volume element yields only once at the first specific load in the invention particularly stressed part without rewinding elastic again when rewinding the roofing element. It then allows a simple but effective individual shaping of the winding shaft, the shape of which then corresponds to the winding requirements of the specific construction of the roofing element.
Die Erfindung betrifft eine aufroilbare Bedachungsinstallation, umfassend eine The invention relates to a rooftop roofing installation comprising a
Wickelwelte und ein stoffartiges Bedachungselement in der sich mindestens ein dauerelastisches und den Wickelradius zunächst vergrößerndes Volumenelement befindet. Das dauereiastische Volumenelement gewährleistet, dass beim Aufwickeln von stoffartigen Bedachungselementen häufig entstehende ungleiche Tuchspannungen direkt durch das elastische Nachgeben des Volumeneiementes wieder ausgeglichen werden, indem es solange nachgibt, bis sich der Wickeldruck zwischen Wickelwelie und Bedachungselement wieder gleichmäßig auf der Welle verteilt und/oder bis die Zugspannung zwischen allen Bereiche des Bedachungselements und der Wickelwelle wieder gleichmäßig Ist Wickelwelte and a fabric-like roofing element in which there is at least one permanently elastic and the winding radius initially magnifying volume element. Ensures the durable elastic volume element that when winding fabric-like roofing elements often resulting unequal fabric tensions are compensated directly by the elastic yielding of the volume element again by it gives way until the winding pressure between Wickelwelie and roofing evenly distributed on the shaft and / or until the Tensile stress between all areas of the roofing element and the winding shaft is uniform again

Figur 1 zeigt schematisch einen Längsschnitt durch eine Wickelwelle 1 mit einem mit zwei Umdrehungen aufgewickelten Bedachungselement 2, wie zum Beispiel einem Markisen- oder Sonnensegeltuch. Der umnähte und dadurch dreitägige seitliche Figure 1 shows schematically a longitudinal section through a winding shaft 1 with a wound with two turns roofing element 2, such as an awning or canvas canvas. The seamed and therefore three-day lateral
Kantenbereich 11 des Bedachungselementes 2 zeigt hier bereits bei zwei 2 Umwicklungen auf der Wickelwelle 2 die Verursachung eines deutlich größeren Wickelradius 10, als den kleineren Wickelradius 13, der von dem einlagig aufgewickelte Bereich 14 des Bedachungselementes 2 verursacht wird. Figur 2 zeigt schematisch einen Längsschnitt durch eine Wickelwelle 1 , die mit einem elastischen Volumenelement 3 versehen ist und auf der wie in Figur 1 ein Badachungs- element 2 mit zwei Umdrehungen der Wickelwelle aufgewickelt ist. Der umnähte und dadurch dreitägige seitliche Kantenbereich 11 des Bedachungselementes 2 zeigt hier, wie er keinen größeren Wickelradius als der übrige einlagig gewickelte Bereich 14 des Bedachungseiementes aufbaut, sondern wie er an Steile dessen das Volumenelement in seinem Wickefbereich derart komprimiert, dass der äußere Wickelradius entlang der Wickeiweile dabei annähernd gieich groß bleibt. Edge region 11 of the roofing element 2 shows here already at two 2 wraps on the winding shaft 2 causing a significantly larger winding radius 10, as the smaller winding radius 13, which is caused by the single-layer wound area 14 of the roofing element 2.

Figur 4 zeigt schematisch einen Querschnitt durch eine weitere mögliche Anordnung der Erfindung mit einer Wickelwelle 1, die mit einer Kedernut versehen ist. in der das Bedachungselement 2 mit einem Kederprofil 8 befestigt ist und das mit 2 Umdrehungen über ein auf der Wickelweile 1 angebrachtes elastisches Volumenelement 3, das hier als schlauchartiger, elastischer und geschlossener mit Gas befüllter Hohlraum 4 dargestellt ist, aufgewickelt ist. Figure 4 shows schematically a cross section through a further possible arrangement of the invention with a winding shaft 1, which is provided with a Kedernut. in which the roofing element 2 is fastened with a keder profile 8 and which is wound with 2 revolutions over an elastic volume element 3, which is shown here as a hose-like, elastic and closed gas-filled cavity 4 on the winding coil 1.
Figur 5 zeigt schematisch einen Querschnitt durch eine weitere mögliche Anordnung der Erfindung mit einer Wickeiweile 1 , die mit einer Kedernut versehen ist, in der das Bedachungselement 2 mit einem Kederprofil 8 befestigt ist und das mit 2 Umdrehungen auf der Wickeiweile aufgewickelt ist. Im noch nicht aufgewickelten Bereich des Figure 5 shows schematically a cross section through a further possible arrangement of the invention with a Wickeiweile 1, which is provided with a Kedernut in which the roofing element 2 is fixed with a Kederprofil 8 and which is wound with 2 turns on the Wickeiweile. In the not yet wound up area of the
Bedachungseiementes 2 befindet sich eine taschenartige Aufnahme 6, in der ein Spannprofil 7 eingebracht ist, das von einem schlauchartigen elastischen Material umgeben ist, wobei dieser Schlauch hier als geschiossenzelllger Kunststoffschaumstoff 4 dargestellt ist. Figur 6 zeigt in der Aufsicht eine schematische Darstellung eines rechteckigen Sonnensegels als Bedachungselement 2, das an einer Wickelwelle 1 befestigt und abgewickelt über ein Zugprofil 15 und daran befestigten Zugseilen 9 gespannt ist. In der Fläche des aufrollbaren Bedachungselements 2 befinden sich in etwa parallel zur Wickelweile vier taschenartige Aufnahmen 6, die wie bereits in Figur 5 gezeigt aufgebaut und beinhaltet sein können oder die einfach nur jeweils ein elastisches Volumenelement 3 beinhatten. Roofing element 2 is a pocket-like receptacle 6, in which a clamping profile 7 is introduced, which is surrounded by a tubular elastic material, this tube is shown here as geschiossenzelllger plastic foam 4. Figure 6 shows in plan view a schematic representation of a rectangular sun shade as roofing element 2, which is attached to a winding shaft 1 and unwound over a tension profile 15 and tension cables 9 attached thereto is tensioned. In the surface of the roll-up roofing element 2 are four pocket-like receptacles 6, which may be constructed and contained as already shown in Figure 5 or approximately just in parallel to the winding time or simply just a respective elastic volume element 3 beinhatten.
