Description

Die Erfindung betrifft eine Vorrichtung zum Verschließen einer seitlichen Öffnung in der Außenhaut oder Wandung eines Bootes. Aus DE 38 15 138 A1 zählt es zum Stand der Technik eine Frachtraumöffnung im Deck eines Schiffes statt mit einer schweren aus Stahl bestehenden Abdeckung mit einem selbsttragenden Abdecksack zu verschließen. Dabei ist der Abdecksack so auszubilden, dass sowohl Regen als auch Spritzwasser sicher abgeführt wird, d. h. nicht durch die Öffnung in den Laderaum eindringen kann. Zur Abdeckung einer seitlichen Öffnung eines Schiffes, insbesondere auch eines militärisch genutzten Schiffes, ist ein solcher Abdecksack allerdings nicht geeignet, da er den auf die Seite eines Schiffes möglicherweise einwirkenden hohen Kräften von Wind und Wellenschlag nicht Stand halten kann. Auch ist die Abdeckung aufgrund ihrer konvexen Außenform hinsichtlich ihrer Radarreflektionseigenschaften ungünstig. Schließlich ist die dort offenbarte Konstruktion nicht geeignet um automatisiert schnell ein motorisch unterstütztes Öffnen oder Schließen der Öffnung zu ermöglichen.The invention relates to a device for closing a lateral opening in the outer skin or wall of a boat. Out DE 38 15 138 A1 It is the state of the art to close a cargo compartment opening in the deck of a ship instead of using a heavy steel cover with a self-supporting cover bag. In this case, the Abdecksack is to be designed so that both rain and splash water is safely dissipated, ie can not penetrate through the opening in the hold. However, to cover a lateral opening of a ship, especially a military-used ship, such a cover bag is not suitable because it can not hold the possibly acting on the side of a ship high forces of wind and waves. Also, the cover is unfavorable in terms of Radarreflektionseigenschaften due to its convex outer shape. Finally, the construction disclosed therein is not suitable for automatically enabling fast motor-assisted opening or closing of the opening.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zum Verschließen einer seitlichen Öffnung in der Außenhaut oder Wandung eines Bootes zu schaffen, die die vorgenannten Nachteile vermeidet oder zumindest vermindert.Against this background, the invention has for its object to provide a device for closing a lateral opening in the outer skin or wall of a boat, which avoids the aforementioned disadvantages or at least reduced.

Die Aufgabe wird gemäß der Erfindung durch die in Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen, der nachfolgenden Beschreibung und der Zeichnung angegeben.The object is achieved according to the invention by the features specified in claim 1. Advantageous embodiments of the invention are set forth in the subclaims, the following description and the drawing.

Die erfindungsgemäße Vorrichtung zum Verschließen einer seitlichen Öffnung in der Außenhaut oder Wandung eines Bootes, insbesondere zum Verschließen einer durch eine Bootsnische gebildete Öffnung, ist mit einem über nahezu die gesamte Öffnung erstreckbaren Stoff versehen, der zur Freigabe der Öffnung von dieser entfernbar ist. Die Vorrichtung weist ferner eine Führung auf, die sich längs zwei gegenüberliegender Seiten der Öffnung erstreckt und den Stoff an zwei Seiten aufnimmt und hält. Teil der Vorrichtung bildet mindestens eine Spannvorrichtung, mit welcher der Stoff in einer Richtung quer zur Führung spannbar ist.The device according to the invention for closing a lateral opening in the outer skin or wall of a boat, in particular for closing an opening formed by a boat niche, is provided with a material which can be extended over almost the entire opening and which can be removed from the latter to release the opening. The apparatus further includes a guide extending along two opposite sides of the opening and receiving and holding the fabric on two sides. Part of the device forms at least one clamping device, with which the fabric in a direction transverse to the guide can be tensioned.

Grundgedanke der erfindungsgemäßen Vorrichtung ist eine Stoffabdeckung der Öffnung, die zum Öffnen entfernbar ist und beispielsweise seitlich aufstaubar ist, jedoch in geschlossenem Zustand die Öffnung nahezu vollständig abdeckt, innerhalb der Öffnung an zwei gegenüberliegenden Seiten geführt und quer zur Führung gespannt ist. Hierdurch kann bei geeigneter Stoffwahl und Ausgestaltung der Vorrichtung ein wandartiger Verschluss der Öffnung hergestellt werden, der aufgrund der Spannung im Wesentlichen in einer Ebene liegt, sodass bei entsprechender Ausgestaltung des Stoffes sehr günstige Radarreflektionseigenschaften erzielt werden. Dadurch, dass der Stoff gespannt ist, kann bei geeigneter Stoffwahl ein Verschluss der Öffnung erzielt werden, der ausreichend widerstandsfähig gegen Seeschlag und Wind ist. Darüber hinaus kann ein solch vorhangartiger Stoff zum Zwecke des Öffnens motorisch entfernt und seitlich oder in der Nische selbst gestaut werden. In der erfindungsgemäßen Vorrichtung können nicht nur Öffnungen in der Außenhaut eines Schiffes, wie sie beispielsweise durch eine Nische gebildet sind, verschlossen werden, sondern auch seitliche Öffnungen in anderen Wandungen, z. B. in Wandungen von Aufbauten. Es handelt sich dabei typischerweise um Öffnungen, die schnell verschlossen und wieder geöffnet werden müssten, beispielsweise zum Lagern von Gangways, von Rettungsbooten, von Beibooten und dergleichen. Diese Öffnungen brauchen meist nicht hermetisch dicht verschlossen zu sein, es genügt in der Regel ein ausreichend fester Spritzwasserschutz mit der Möglichkeit, das im Randbereich eindringende Wasser durch vorzugsweise einen natürlichen Abfluss wieder herauszufördern. Typischerweise dient die Vorrichtung zum Abdecken von seitlichen Öffnungen rechteckiger Form, sie ist jedoch keinesfalls darauf beschränkt. Dabei ist die Führung vorteilhaft so angeordnet, dass sie in der Richtung verläuft, in der die größte Längserstreckung der Öffnung gegeben ist. In der Regel dürfte dies beispielsweise bei einer Öffnung in der Außenhaut die Erstreckung in Längsrichtung des Bootes sein.The basic idea of the device according to the invention is a fabric cover of the opening, which is removable for opening and, for example, can be laterally stowed, but in the closed state almost completely covers the opening, guided inside the opening on two opposite sides and stretched transversely to the guide. In this way, with a suitable choice of material and design of the device, a wall-like closure of the opening can be produced, which lies substantially in one plane due to the tension, so that with appropriate design of the substance very favorable Radarreflektionseigenschaften can be achieved. Because the fabric is stretched, a closure of the opening can be achieved with a suitable choice of material, which is sufficiently resistant to sea fog and wind. In addition, such a curtain-like fabric can be removed by motor for the purpose of opening and stowed laterally or in the niche itself. In the device according to the invention not only openings in the outer skin of a ship, as they are formed for example by a niche, can be closed, but also lateral openings in other walls, for. B. in walls of Superstructures. These are typically openings that need to be quickly closed and reopened, for example for storing gangways, lifeboats, dinghies and the like. These openings usually do not need to be hermetically sealed, it is usually sufficient to a sufficiently solid splash water protection with the ability to promote the penetrating water in the edge region by preferably a natural outflow again. Typically, the device serves to cover lateral openings of rectangular shape, but is by no means limited thereto. In this case, the guide is advantageously arranged so that it runs in the direction in which the greatest longitudinal extent of the opening is given. As a rule, this should be the extension in the longitudinal direction of the boat, for example, in the case of an opening in the outer skin.

Gemäß einer vorteilhaften Weiterbildung der Erfindung, weist die Führung zwei gegenüberliegende Schienen auf, zwischen denen der Stoff gehalten und geführt ist. Diese Schienen erstrecken sich vorzugsweise in Längsrichtung der Öffnung, können jedoch gegebenenfalls in anderer Richtung verlaufen. Eine solche Führung ist konstruktiv einfach aufgebaut und arbeitet wie ein zweiseitig geführter Vorhang, sodass der Stoff an zwei Seiten geführt und gehalten ist, wobei die Spannvorrichtung eine Kraft quer zu den Schienen aufbaut um den Stoff in einer Ebene zu halten und die erforderliche Widerstandskraft gegen Wind und Wellenschlag von außen aufzubauen.According to an advantageous embodiment of the invention, the guide has two opposite rails, between which the fabric is held and guided. These rails preferably extend in the longitudinal direction of the opening, but may optionally extend in a different direction. Such a guide is structurally simple and works like a two-sided curtain, so that the fabric is guided and held on two sides, the tensioning device builds a force across the rails to keep the fabric in a plane and the required resistance to wind and build up waves from the outside.

Wenn die Führung durch zwei Schienen gebildet ist, dann ist es konstruktiv besonders günstig, eine der Schienen zumindest in Spannrichtung bootsfest und die andere Schiene zumindest in Spannrichtung bewegbar anzuordnen, wobei zweckmäßigerweise zumindest ein Spannelement zwischen der bewegbaren Schiene und einem bootsfestem Teil vorgesehen ist. Bei geeigneter Konstruktion wird man zumindest eine der beiden Schienen nicht nur in Spannrichtung bootsfest sondern in allen Richtungen bootsfest anordnen, also fest mit dem Bootskörper verbinden. Die andere Schiene muss gegebenenfalls zum Ausgleich von Toleranzen in einem gewissen Maße beweglich sein, was gegebenenfalls auch über das Spannelement erfolgen kann.If the guide is formed by two rails, then it is structurally particularly favorable, at least one of the rails in the tensioning boatfest and the other rail at least to arrange movable in the tensioning direction, expediently at least one clamping element between the movable rail and a boatfestem part is provided. With a suitable construction, at least one of the two rails will not only be boat-fixed in the tension direction, but also Arrange boatfest in all directions, so connect firmly to the hull. If necessary, the other rail must be movable to a certain extent to compensate for tolerances, which may optionally also take place via the tensioning element.

Als Spannelement können über die Länge der Führung verteilt Zylinder oder andere motorisch verstellbare Linearantriebe angeordnet sein. Besonders vorteilhaft ist ein gemeinsames Spannelement vorgesehen, das zwar nach dem Wirkprinzip eines Druckzylinders, insbesondere Hydraulikzylinder aufgebaut ist, sich jedoch über die Länge der damit verbundenen Schienen erstreckt. Ein solches Spannelement kann, wie nachfolgend noch im Einzelnen beschrieben wird, in konstruktiv wenig aufwendiger Weise bereitgestellt werden und ermöglicht dann gegebenenfalls auch den vorerwähnten Längen- bzw. Toleranzausgleich der daran befestigten Schiene, d. h. dass die Ausfahrbewegung des Zylinders nicht überall gleich sein muss, sondern durch den hydraulischen Antrieb insoweit gegebene Toleranzen selbsttätig ausgeglichen werden können.As a clamping element distributed over the length of the guide cylinder or other motor-adjustable linear actuators can be arranged. Particularly advantageous is a common clamping element is provided which, although constructed according to the operating principle of a printing cylinder, in particular hydraulic cylinder, but extends over the length of the associated rails. Such a clamping element can, as will be described in detail below, be provided in a structurally less complicated manner and then optionally also allows the aforementioned length or tolerance compensation of the rail attached thereto, d. H. that the extension movement of the cylinder does not have to be the same everywhere, but can be compensated by the hydraulic drive insofar given tolerances automatically.

Hierzu ist gemäß einer Weiterbildung der Erfindung vorgesehen, den Druckraum des Spannelementes durch mindestens ein elastisches schlauchförmiges Gefäß zu bilden, das durch demgegenüber starre und zueinander bewegliche Wände des Spannelementes abgestützt ist. Eine solche Ausbildung hat den Vorteil, dass das Spannelement selbst nicht mit hoher Präzision zu fertigen und mit Dichtungen zu versehen ist, da diese Funktion durch das in das Spannelement eingegliederte elastische Gefäß erfolgt. Dabei ist insbesondere ein solches Gefäß dazu geeignet, sich über die Länge unterschiedlich auszudehnen und somit Toleranzen auszugleichen.For this purpose, according to a further development of the invention, it is provided to form the pressure chamber of the tensioning element by at least one elastic tubular vessel which is supported by walls of the tensioning element that are rigid and movable relative to one another. Such a design has the advantage that the clamping element itself can not be manufactured with high precision and provided with seals, since this function is performed by the incorporated into the clamping element elastic vessel. In particular, such a vessel is suitable to expand differently over the length and thus compensate for tolerances.

Vorteilhaft weist das Spannelement ein etwa quaderförmiges Gehäuse auf, das einen sich über die Länge des Gehäuses in einer Gehäuseseite erstreckenden Schlitz aufweist. Durch diesen Schlitz ist der Steg eines innerhalb des Gehäuse in Spannrichtung beweglich gelagerten T-Trägers geführt, der sich über die gesamte Länge des Gehäuses erstreckt und der durch zwei innerhalb des Gehäuses angeordnete elastische schlauchförmige Gefäße, die jeweils an einer Seite des Stegs anliegen und den Druckraum des Spannelementes bilden, beaufschlagt ist. Je nach Füllung dieser Gefäße fährt somit dieser Steg des T-Trägers aus dem Gehäuse aus bzw. in das Gehäuse ein. Dabei sorgt die Gefäßanordnung dafür, dass die Kraftverteilung auf den T-Träger über die Länge des Spannelementes stets gleichmäßig ist.Advantageously, the clamping element has an approximately cuboid housing, which extends over the length of the housing in a housing side having extending slot. Through this slot, the web of a movably mounted within the housing in the clamping direction T-beam is guided, which extends over the entire length of the housing and by two disposed within the housing elastic tubular vessels, which abut respectively on one side of the web and the Form pressure chamber of the clamping element, is acted upon. Depending on the filling of these vessels, this web of the T-carrier thus moves out of the housing or into the housing. The vessel arrangement ensures that the force distribution on the T-beam over the length of the clamping element is always uniform.

Zwar ist die Kinematik zwischen T-Träger und Gehäuse im Bezug auf die Vorrichtung grundsätzlich beliebig, doch hat es sich als vorteilhaft erwiesen, das Gehäuse bootsfest anzuordnen und am gehäusefernen Ende des Stegs des T-Trägers die eine Schiene der Führung zu befestigen, sodass je nach Ausfahrstellung des T-Trägers der Abstand der gegenüberliegenden Schienen größer oder kleiner ist. Es kann also durch Druckbeaufschlagung der Gefäße der T-Träger mit seinem Steg in das Gehäuse eingefahren werden, wodurch die daran befestigte Schiene ihren Abstand zur gegenüberliegenden Schiene vergrößert und der dazwischen befindliche Stoff gespannt wird. Durch Druckentlastung der Gefäße wird der Stoff entspannt.Although the kinematics between the T-beam and housing with respect to the device is basically arbitrary, but it has proven to be advantageous to arrange the housing bootsfest and attach to the housing distal end of the web of the T-beam, the one rail of the guide, so ever after extending position of the T-beam, the distance between the opposite rails is larger or smaller. It can therefore be retracted by pressurizing the vessels of the T-beam with its web in the housing, whereby the rail attached thereto increases its distance from the opposite rail and the substance located therebetween is tensioned. By relieving the pressure on the vessels, the substance is released.

Um die Öffnung schnell freizugeben und wieder verschließen zu können und dabei den Stoff raumsparend zu stauen, ist gemäß einer Weiterbildung der Erfindung vorgesehen, den Stoff auf einer Trommel aufrollbar zu lagern, sodass bei geöffneter Öffnung der Stoff auf der Trommel aufgewickelt und bei verschlossener Öffnung weitgehend von dieser abgewickelt ist.In order to release the opening quickly and close it again while storing the fabric to save space, is provided according to a further development of the invention to store the fabric on a drum rollable, so wound with the opening open the fabric on the drum and largely closed at opening is handled by this.

Konstruktiv besonders günstig ist es dabei die Trommel bootsfest zu lagern und mit einem motorischen Antrieb zu versehen, der zumindest in Aufwickelrichtung wirksam ist. Da die Spannvorrichtung hydraulisch arbeitet, ist es zweckmäßig, auch den Antriebsmotor der Trommel als hydraulischen Motor auszulegen. Derartige Motoren sind darüber hinaus sehr kompakt und wenig anfällig gegenüber Umwelteinflüssen, wie hier insbesondere Seewasser.It is particularly advantageous in terms of design to store the drum in a boat-proof manner and to provide it with a motor drive which is at least in Winding is effective. Since the clamping device operates hydraulically, it is expedient to design the drive motor of the drum as a hydraulic motor. In addition, such motors are very compact and less susceptible to environmental influences, in particular seawater.

Um den Stoff von der Trommel abzuwickeln, sind gemäß einer Weiterbildung der Erfindung an der der Trommel gegenüberliegenden Seite der Öffnung mindestens eine, vorzugsweise jedoch zwei Seilwinden vorgesehen, deren Seile vorteilhaft längs der Schiene der Führung verlaufen und am freien Ende des Stoffs angreifen, sodass bei Antrieb der Seilwinden in Aufwickelrichtung der Seile der Stoff von der Trommel abgezogen wird und die Öffnung verschließt. Auch die Seilwinden sollten vorteilhaft einen hydraulischen Antrieb aufweisen. Zum Zwecke des Abwickelns von der Trommel ist diese soweit zu lösen, dass sie drehbar ist, bzw. der Antrieb entgegen Aufwickelrichtung arbeitet.To unwind the fabric from the drum, at least one, but preferably two winches are provided according to an embodiment of the invention on the opposite side of the drum, the ropes advantageously along the rail of the guide and attack the free end of the fabric, so at Driving the winches in the winding direction of the ropes the fabric is pulled off the drum and closes the opening. The winches should advantageously have a hydraulic drive. For the purpose of unwinding from the drum, this is to be solved so far that it is rotatable, or the drive works against the winding direction.

Um dem Stoff bei verschlossener Öffnung eine hohe Widerstandskraft gegen Wind und Wellenschlag zu verschaffen, ist es zweckmäßig nicht nur diesen zwischen der Führung, also zwischen den Schienen zu spannen, sondern auch in Querrichtung zumindest zu halten oder gegebenenfalls mit einer voreinstellbaren Kraft zu beaufschlagen. Hierzu ist gemäß einer Weiterbildung der Erfindung vorgesehen, die Hydraulikantriebe für das Aus- und Abwickeln des Stoffs feststellbar auszubilden oder aber mit voreinstellbarer Kraft zueinander gegenläufig zu beaufschlagen, um auch in Querrichtung zur Spannrichtung eine gewisse Zugkraft aufzubauen.In order to provide the substance with a closed opening a high resistance to wind and waves, it is expedient not only to stretch this between the guide, ie between the rails, but also in the transverse direction at least to hold or optionally to apply a presettable force. For this purpose, according to a further development of the invention, the hydraulic drives for the unwinding and unwinding of the fabric detectable train or act on each other with presettable force in opposite directions to build up a certain tensile force in the transverse direction to the clamping direction.

Um die eingangs geforderten Eigenschaften des Stoffs bei verschlossener Öffnung zu erreichen, ist es zweckmäßig, den Stoff mehrlagig aufzubauen, um auf diese Weise Materialeigenschaften unterschiedlicher Lagen synergetisch zu kombinieren. So ist gemäß der Erfindung insbesondere für den militärischen Einsatz der Stoff mit einer Reflektionsschicht, in Form einer Metallfolie versehen.. Ein so beschaffener Stoff in Verbindung mit der Spannvorrichtung, die dafür sorgt, dass der Stoff im Wesentlichen in einer Ebene mit der Wandung liegt, ist hervorragend geeignet, um die Radarerkennbarkeit des Bootes, insbesondere im Bereich der Öffnung zu vermindern.In order to achieve the initially required properties of the substance when the opening is closed, it is expedient to construct the material in multiple layers in order to synergistically combine material properties of different layers in this way. Such is in particular according to the invention For military use, the fabric is provided with a reflective layer, in the form of a metal foil. Such a fabric in conjunction with the tensioning device, which ensures that the substance lies substantially in one plane with the wall, is ideally suited to the Radar recognition of the boat, especially in the area of the opening to reduce.

Weiterhin ist es zweckmäßig, den Stoff mit einer UV-stabilen Beschichtung zu versehen. Eine solche UV-Schutzschicht kann beispielsweise durch eine an der Außenseite des Stoffs auflaminierte Taffeta-Lage gebildet sein.Furthermore, it is expedient to provide the substance with a UV-stable coating. Such a UV protective layer may be formed, for example, by a taffeta layer laminated to the outside of the fabric.

Der Stoff selbst muss einerseits eine gewisse Elastizität haben. Andererseits muss er jedoch eine ausreichende Zugfestigkeit haben, damit er mit der erforderlichen Kraft gespannt werden kann und so den äußeren Einflüssen ohne merkliche Veränderung in seiner Form standhalten zu können. Dabei hat sich grundsätzlich ein Aufbau aus mehrlagigem Segeltuch als vorteilhaft erwiesen. Um die erforderlichen Zugkräfte aufzunehmen, ist es zweckmäßig, den Stoff mit hochzugfesten Fasern zu armieren, wie beispielsweise Kohlefasern.The fabric itself must have a certain elasticity on the one hand. On the other hand, however, it must have sufficient tensile strength so that it can be tensioned with the required force and thus be able to withstand the external influences without noticeable change in its shape. In principle, a multi-layered canvas structure has proven to be advantageous. In order to absorb the required tensile forces, it is desirable to reinforce the fabric with high tensile strength fibers such as carbon fibers.

Um die Verbindung von Stoff und Schiene ausreichen stabil zu gestalten, ist gemäß einer Weiterbildung der Erfindung der Stoff zumindest an seinen schienenseitigen Rändern verstärkt ausgebildet und dort mit Kulissensteinen versehen, die an oder in den Schienen formschlüssig geführt sind.In order to make the connection of fabric and rail sufficiently stable, according to an embodiment of the invention, the fabric is reinforced at least on its rail-side edges and provided there with sliding blocks, which are guided positively on or in the rails.

Das in Fig. 1 dargestellte Boot 1 weist im Bereich seiner in Längsrichtung des Bootes verlaufenden Bootswandung 2 eine Nische 3 auf, durch die eine Öffnung 4 in der Bootswandung 2 gebildet ist. Diese Öffnung 4 in der Wandung 2 des Bootes 1 kann mittels einer Stoffbahn 5 verschlossen werden, die auf einer Trommel 6 am Rande der Öffnung 4 innerhalb der Nische 3 aufgestaut ist. Die Öffnung 4 weist in Längsrichtung 7 eine deutlich größere Erstreckung als in Querrichtung dazu auf. Die Trommel 6 erstreckt sich mit ihrer Drehachse in Querrichtung zur Längsrichtung 7. Sie ist innerhalb der hier quaderförmigen Nische 3 zwischen Decke 8 und Boden 9 gelagert. Sie ist in die Nische hinein gebaut.This in Fig. 1 illustrated boat 1 has in the region of its running in the longitudinal direction of the boat boat wall 2 a niche 3, through which an opening 4 is formed in the boat wall 2. This opening 4 in the wall 2 of the boat 1 can be closed by means of a fabric web 5, which is dammed on a drum 6 at the edge of the opening 4 within the niche 3. The opening 4 has a significantly greater extent in the longitudinal direction 7 than in the transverse direction thereto. The drum 6 extends with its axis of rotation in the transverse direction to the longitudinal direction 7. It is stored within the here cuboid niche 3 between the ceiling 8 and bottom 9. She is built into the niche.

Die auf der Trommel 6 aufgewickelte Stoffbahn 5 ist zunächst über eine parallel zur Trommel 6 nahe der Öffnung 4 angeordnete Umlenkrolle 10 geführt und erstreckt sich von dort über die Öffnung 4 bis zum anderen Ende der Öffnung. Dort sind gegenüber der Öffnung 4 in der Nische 3 nach innen versetzt zwei hydraulisch angetriebene Seilwinden 11 und 12 angeordnet, deren Seile zunächst nahe der Decke 8 bzw. dem Boden 9 umgelenkt und dort in Schienen 13 und 14 geführt sind, die eine Führung für die Stoffbahn 5 nahe der Decke 8 und dem Boden 9 in Längsrichtung 7 der Öffnung 4 bilden. Die freien Enden der Seile der Seilwinden 11 und 12 greifen nahe den Ecken am freien Ende der Stoffbahn 5 an.The wound on the drum 6 fabric 5 is first guided over a parallel to the drum 6 near the opening 4 arranged deflection roller 10 and extends from there via the opening 4 to the other end of the opening. There are opposite the opening 4 in the niche 3 offset inwardly two hydraulically driven winches 11 and 12 whose ropes are initially deflected near the ceiling 8 and the bottom 9 and guided therein in rails 13 and 14, which form a guide for the fabric 5 near the ceiling 8 and the bottom 9 in the longitudinal direction 7 of the opening 4. The free ends of the cables of the winches 11 and 12 engage near the corners at the free end of the panel 5.

Die Seilwinden 11 und 12 weisen Hydraulikmotoren auf und dienen Primär zum Abwickeln der Stoffbahn 5 von der Trommel 6 zum Verschlie-βen der Öffnung 4. In umgekehrter Richtung, also zum Aufwickeln der Stoffbahn 5 und zum Freistellen der Öffnung 4 weist die Trommel 6 einen hydraulischen Antrieb auf, der in Fig. 5 im einzelnen dargestellt und weiter unten noch beschrieben ist.The winches 11 and 12 have hydraulic motors and are primary for unwinding of the fabric web 5 from the drum 6 for closing the opening 4. In the reverse direction, that is, for winding the web 5 and for releasing the opening 4, the drum 6 has a hydraulic Drive on, in Fig. 5 shown in detail and will be described below.

Die Schienen 13 und 14 erstrecken sich nahe den oberen und unteren Rändern der Öffnung 4 und führen die Stoffbahn 5 in Längsrichtung. Hierzu sind an den Längsrändern der Stoffbahn, wie aus Fig. 4 ersichtlich ist, Kulissensteine 15 angebracht, welche einerseits mit dem verstärkten Rand der Stoffbahn 5 verbunden sind und andererseits formschlüssig in der unteren bzw. oberen Schiene 13, 14 geführt sind. Die Kulissensteine 15 sind zur Schiene hin im Querschnitt T-förmig ausgebildet, wobei der Steg durch einen Schlitz der Schiene durchgeführt ist und der quer dazu verlaufende Teil innerhalb der Schiene 14 geführt ist.The rails 13 and 14 extend near the upper and lower edges of the opening 4 and guide the web 5 in the longitudinal direction. For this purpose, at the longitudinal edges of the fabric, as out Fig. 4 it can be seen, sliding blocks 15 attached, which are on the one hand connected to the reinforced edge of the panel 5 and on the other hand positively in the lower or upper rail 13, 14 are guided. The sliding blocks 15 are formed to the rail in cross-section T-shaped, wherein the web is performed by a slot of the rail and the transverse thereto extending part is guided within the rail 14.

Die obere Schiene 13 ist an der Decke 8 fest angebracht, die untere Schiene 14 hingegen, die sich ebenfalls über nahezu die gesamte Länge der Öffnung 4 erstreckt, ist an einer Spannvorrichtung in Form eines hydraulischen Spannelementes 16 angebracht. Dieses hydraulische Spannelement 16 erstreckt sich über die gesamte Länge der Schiene 14 und besteht aus einem quaderförmigen im Querschnitt nahezu quadratischen Gehäuse 17, das an seiner Oberseite mit einem sich über etwa die gesamte Länge des Gehäuses erstreckenden Schlitz 18 versehen ist, durch den ein Steg 19 eines darin beweglich gelagerten T-Trägers 20 geführt ist. Das freie Ende des Stegs 19 ist fest mit der unteren Schiene 14 verbunden.The upper rail 13 is fixed to the ceiling 8, the lower rail 14, however, which also extends over almost the entire length of the opening 4, is attached to a clamping device in the form of a hydraulic tensioning element 16. This hydraulic tensioning element 16 extends over the entire length of the rail 14 and consists of a cuboidal in the cross section almost square housing 17 which is provided on its upper side with a extending over about the entire length of the housing slot 18, through which a web 19 of a movably mounted therein T-beam 20 is guided. The free end of the web 19 is fixedly connected to the lower rail 14.

Darüber hinaus ist eine Dichtmanschette 21 vorgesehen, welche einerseits am Gehäuse 17 und andererseits an der Schiene 14 anschließt und den dazwischen liegenden Raum abdichtet. Benachbart zu dem Steg 19 des T-Trägers 20 liegt in dem durch die oberen und seitlichen Seiten des Gehäuses 17 einerseits und durch den T-Träger 20 andererseits begrenzten Raum jeweils ein lang gestrecktes elastisches schlauchförmiges Gefäß 22, welches hydraulisch beaufschlagbar ist. Wenn die beiden hydraulisch miteinander verbundenen Gefäße 22 mit Hydraulikflüssigkeit druckbeaufschlagt werden, dehnen sich diese aus. Dies ist allerdings wegen der starren Wände des Gehäuses 17 des ebenfalls starren T-Trägers 20 nur in eine Richtung 23 quer zur Längsrichtung 7 möglich, wodurch der T-Träger 20 innerhalb des Gehäuses 17 nach unten gedrückt wird. Mit diesem wandert auch die Schiene 14 nach unten, wodurch die zwischen der oberen Schiene 13 und der unteren Schiene 14 in Schließstellung befindliche Stoffbahn 5 in Richtung 23 gespannt wird.In addition, a sealing collar 21 is provided which connects on the one hand to the housing 17 and on the other hand to the rail 14 and seals the space between them. Adjacent to the web 19 of the T-beam 20 is in the through the upper and lateral sides of the housing 17 on the one hand and by the T-beam 20 on the other hand limited space each an elongated elastic tubular vessel 22 which is hydraulically acted upon. When the two hydraulically interconnected vessels 22 are pressurized with hydraulic fluid, they expand. However, this is possible because of the rigid walls of the housing 17 of the likewise rigid T-beam 20 only in a direction 23 transversely to the longitudinal direction 7, whereby the T-beam 20 is pressed within the housing 17 down. With this also moves the rail 14 down, causing the located between the upper rail 13 and the lower rail 14 in the closed position fabric 5 is tensioned in the direction 23.

Da die Gefäße 22 sich über die gesamte Länge des Gehäuses 17 und somit auch der Schiene 14 erstrecken, werden durch die Hydraulik selbsttätig Toleranzen, welche durch die Form der Stoffbahn oder die Anordnung der Schienen 13, 14 bedingt sind, ausgeglichen. Ebenso ist sichergestellt, dass die Zugkräfte ausschließlich in Querrichtung zur Richtung 7 in der Stoffbahn 5 verlaufen.Since the vessels 22 extend over the entire length of the housing 17 and thus also the rail 14, the hydraulics automatically tolerances, which are due to the shape of the fabric or the arrangement of the rails 13, 14 compensated. It is also ensured that the tensile forces extend only in the transverse direction to the direction 7 in the fabric 5.

Während die Seilwinden 11 und 12 zum Verschließen der Öffnung in Aufwickelrichtung aktiviert werden, ist die Trommel 6 über einen in Fig. 5 im Einzelnen dargestellten hydraulischen Antrieb in Aufwickelrichtung zu aktivieren, um die Öffnung 4 freizugeben. Wie die Fig. 5 verdeutlicht, ist die Trommel 6 nahe ihrem unteren Ende mit einem Kettenrad 24 verbunden, welches von einem neben der Trommellagerung angeordneten Hydraulikmotor 25 antreibbar ist.While the winches 11 and 12 are activated to close the opening in the winding, the drum 6 via an in Fig. 5 to activate in detail shown in the take-up hydraulic drive to release the opening 4. As the Fig. 5 illustrates, the drum 6 is connected near its lower end with a sprocket 24, which is drivable by a arranged next to the drum bearing hydraulic motor 25.

Die Seilwinden 11 und 12 sowie der hydraulische Antrieb 24, 25 der Trommel 6 können nicht nur zum Öffnen und Verschließen der Öffnung 4, d. h. zum Auf- bzw. Abwickeln der Stoffbahn 5 angesteuert werden, sondern auch gegensinnig , sodass eine Zugkraft in Längsrichtung 7 der Stoffbahn 5 aufgebracht wird, wodurch sichergestellt ist, dass die Stoffbahn 5 in abgewickelter, also in Schließstellung, nahezu in einer Ebene verläuft. Sie ist dabei so angeordnet, dass ihre Außenseite etwa in Flucht mit der Bootswandung 2 verläuft.The winches 11 and 12 and the hydraulic drive 24, 25 of the drum 6 can be controlled not only to open and close the opening 4, ie for winding or unwinding of the fabric 5, but also in opposite directions, so that a tensile force in the longitudinal direction 7 of Fabric web 5 is applied, which ensures that the fabric web 5 in unwound, so in the closed position, almost in a plane. It is arranged so that its outer side runs approximately in alignment with the boat wall 2.
