Abstract

According to the invention, inflatable boats with continuous buoyancy tubes forming the boats' side are provided with auxiliary tubes of roughly crescent-shaped cross-sectional configuration attached to the underside of the buoyancy tubes. On the one hand, success is achieved in substantially improving the sailing properties of the inflatable boats, in particular in rough water, and, on the other hand, the special cross-sectional shape of the auxiliary tubes permits simplifications in production. <IMAGE>

Description

Die Erfindung bezieht sich auf Schlauchboote, deren Bordwände von durch ein starres Querwandelement im Heckbereich in gegenseitigem Abstand gehaltenen und im Bugbereich zusammengeführten aufblasbaren Tragschläuchen gebildet sind, wobei zusätzliche aufblasbare Schläuche von im Vergleich zu den Tragschläuchen wesentlich geringerer Querschnittsfläche an deren Unterseite in Längsrichtung mit ihnen durchlaufend vorgesehen sind.The invention relates to inflatable boats, the side walls of which are formed by inflatable support tubes which are held at a distance from one another by a rigid transverse wall element and which are brought together in the bow area, additional inflatable tubes having a substantially smaller cross-sectional area on the underside of them running through them in the longitudinal direction in comparison with the support tubes are provided.

Schlauchboote dieser Art mit im Unterwasserschiff gleichsam nach unten verlängerten Tragschläuchen sind beispielsweise aus der DOS 3 227 104 bekannt. Die in geometrisch ähnlicher Entsprechung zu den Tragschläuchen ebenfalls mit kreisförmigem Querschnitt gestalteten zusätzlichen Schläuche sind dabei in einer gegen die senkrechte Mittelachse der Tragschläuche einwärts versetzten Umfangszone an diesen befestigt und dienen in erster Linie dazu, eine tangential an die Tragschläuche angesetzte äußere Bodenhaut zu spannen und als tragende Flächen für die hydrodynamischen Eigenschaften des Bootskörpers nutzbar zu machen. Von Bedeutung ist hierfür das abgestimmte Zusammenwirken mit einem gegen einen starren Innenboden sich abstützenden und eine äußere Bodenhaut zwischen den Tragschläuchen stumpfwinkelig abspreizenden Kiel. Wenn dieser Bootstyp sich im allgemeinen auch gut bewährt und die in ihn gesetzten Erwartungen durchaus erfüllt hat, so ließ er verschiedentlich doch noch Wünsche nach Verbesserungen offen,da er konstruktionsbedingt bei höheren Geschwindigkeiten einmal im Bodenbereich besonders stark belastet wird und zum anderen mit zunehmender Wellenhöhe in Rauhwasser deutlich an Fahrkomfort verliert.Inflatable boats of this type with carrying hoses extended downward in the underwater ship are known, for example, from DOS 3 227 104. The additional hoses, which have a circular cross-section and are geometrically similar to the support hoses, are fastened to them in a circumferential zone offset inwards from the vertical central axis of the support hoses and serve primarily to tension and as an outer skin attached tangentially to the support hoses to make bearing surfaces usable for the hydrodynamic properties of the hull. What is important for this is the coordinated interaction with a keel that supports itself against a rigid inner floor and an outer floor skin between the support tubes at an obtuse angle. Although this type of boat has generally proven itself well and has fully met the expectations placed on it, it still leaves various wishes for improvements open due to the design, it is subjected to particularly heavy loads in the ground area at higher speeds and, on the other hand, loses driving comfort significantly as the wave height increases in rough water.

Der Erfindung liegt als Aufgabe zugrunde, die bekannten Schlauchboote unter Beibehaltung aller fahrtechnischen Vorzüge durch eine neuartige Gestaltung des Unterwasserschiffes hinsichtlich ihres Fahrverhaltens insbesondere unter extremen Bedingungen weiter zu verbessern und die auftretenden Beanspruchungen möglichst materialgerecht in den Bootskörper einzuleiten. Diese Aufgabe wird, ausgehend von Schlauchbooten der eingangs geschilderten Gattung, erfindungsgemäß dadurch gelöst, daß die zusätzlichen Schläuche im aufgeblasenen Zustand mit einer in Form einer Sichel oder eines Kreiszweieckes von zwei ungleichen Radien umschriebenen, in bezug auf die Tragschläuche konkav gekrümmten Querschnittsgestalt ausgebildet sind. Dabei verläuft die den Tragschläuchen zugekehrte konkave Innenfläche der zusätzlichen Schläuche im wesentlichen nach dem Radius des kreisförmigen oder zumindest angenähert kreisförmigen Querschnittes der Tragschläuche und ihre den Tragschläuchen abgekehrte konvexe freie Außenfläche nach einem im Vergleich dazu kleineren Radius. Gemäß weiteren Teilmerkmalen der Erfindung sind die zusätzlichen Schläuche haftend mit den Tragschläuchen verbunden und umspannen deren Umfang über einen Bogenwinkel in einer Größenordnung zwischen 45° und 90°, vorzugsweise in der Art, daß sie symmetrisch zur senkrechten Mittellinie des Tragschlauchquerschnittes - auf die waagerechte Schwimmlage des Schlauchbootes bezogen - auf dem eingetauchten unteren Umfangsbogen der Tragschläuche und außerhalb des die Tragschläuche untereinander verbindenden Bootsbodens angebracht sind.The invention has for its object to further improve the known inflatable boats while maintaining all the technical advantages of driving a new design of the underwater ship in terms of their driving behavior, especially under extreme conditions, and to introduce the stresses that occur into the boat hull as materially as possible. This object is achieved, starting from inflatable boats of the type described at the outset, in that the additional tubes, when inflated, are designed with a cross-sectional shape that is concavely curved with respect to the supporting tubes in the shape of a sickle or a circle of two unequal radii. The concave inner surface of the additional hoses facing the carrying hoses runs essentially according to the radius of the circular or at least approximately circular cross section of the carrying hoses, and their convex free outer surface facing away from the carrying hoses has a radius which is smaller by comparison. According to further features of the invention, the additional hoses are adhesively connected to the support hoses and span their circumference over an arc angle in the range between 45 ° and 90 °, preferably in such a way that they are symmetrical to the vertical center line of the support hose cross section - on the horizontal floating position of the Inflatable boat-related - are attached to the immersed lower peripheral bend of the carrying hoses and outside of the bottom of the boat connecting the carrying hoses.

Die Erfindung erreicht die angestrebten Verbesserungen mit vergleichsweise einfachen konstruktiven Mitteln. Mit dem neuartigen Sichel- oder etwa Halbmondquerschnitt sind die zusätzlichen Schläuche als sogenannte Halbschläuche in üblicher Weise und mit den üblichen Vorrichtungen ohne besondere Schwierigkeiten herzustellen. Für die Befestigung an den zylindrischen Tragschläuchen bieten sie aufgrund ihrer im ganzen konkaven Formkrümmung eine außerordentlich breite Haftfläche, die den Klebevorgang erleichtert und vereinfacht und selbst noch bei fehlerhafter Ausführung eine hohe Abreißfestigkeit gewährleistet. In ihrer symmetrischen Ausrichtung zu der Querschnittsmitte der Tragschläuche beeinflussen sie, in der Wirkung etwa Kielflossen vergleichbar, unmittelbar den Formfaktor des Unterwasserschiffes, was in der Folge höhere Fahrgeschwindigkeiten auch in Rauhwasser ohne das gefürchtete Springen und Schlagen ermöglicht und eine überraschende Spurtreue in allen Geschwindigkeitsbereichen und beim Durchfahren extrem enger Kurven begründet. Der Fortfall der an bekannten Schlauchbooten vorgesehenen seitlichen Tragflächen vereinfacht dazu noch die Konstruktion und den Fertigungsaufwand, was sich letzten Endes in Kostenersparnissen niederschlägt. Die räumliche und festigkeitsmäßige Trennung der zusätzlichen Schläuche von dem in üblicher Weise zwischen den Tragschläuchen verspannten flexiblen Bootsboden wirkt sich darüber hinaus in einer Verringerung und günstigeren Verteilung der Bodenbeanspruchung vor allem in höheren Geschwindigkeitsbereichen und im durchschnittlichen Beladungszustand aus.The invention achieves the desired improvements with comparatively simple constructive means. With the novel sickle or approximately half-moon cross-section, the additional hoses can be produced as so-called half-hoses in the usual way and with the usual devices without any particular difficulties. Due to their concave shape, they offer an extraordinarily wide adhesive surface for attachment to the cylindrical carrying hoses The gluing process is simplified and simplified, and a high tear-off strength is guaranteed even if the design is incorrect. In their symmetrical alignment with the center of the cross-section of the carrying hoses, they have a direct influence on the form factor of the underwater hull, which is comparable to a keel fin, which consequently enables higher cruising speeds even in rough water without the feared jumping and hitting and a surprising directional stability in all speed ranges and at Driving through extremely tight curves justified. The elimination of the lateral wings provided on known inflatable boats also simplifies the design and the manufacturing effort, which ultimately results in cost savings. The spatial and strength-related separation of the additional hoses from the flexible boat floor clamped in the usual way between the support hoses also results in a reduction and more favorable distribution of the floor stress, especially in higher speed ranges and in the average load condition.

Zweckmäßig werden die zusätzlichen Schläuche aus dem auch für die Tragschläuche verwendeten imprägnierten Gewebe hergestellt. Gemäß einer Variante der Erfindung könnten sie stattdessen aber auch von auswechselbar in formgebende zugfeste Hüllen eingelegten Schlauchkörpern gebildet sein. Dies bietet den Vorteil der leichten, einfachen Austauschbarkeit im Schadensfalle. Die Beschaffenheit und Konstruktion des meistens vorhandenen inneren Einlegebodens sind für die Erfindung ohne Bedeutung, und ebenso ist die Erfindung auch in Verbindung mit nur einem aufblasbaren Luftkammerboden anwendbar.The additional hoses are expediently produced from the impregnated fabric which is also used for the support hoses. According to a variant of the invention, however, they could instead be formed by hose bodies which are interchangeably inserted into shaping, tensile shells. This offers the advantage of easy, simple interchangeability in the event of damage. The nature and construction of the mostly existing inner shelf are of no importance for the invention, and the invention can also be used in connection with only one inflatable air chamber floor.

Die Erfindung ist anhand der schematischen Darstellung zweier Ausführungsbeispiele in der Zeichnung verdeutlicht. In der Zeichnung ist:

  • Fig. 1 ein erfindungsgemäßes Schlauchboot in perspektivischer Ansicht von hinten auf die Bodenfläche;
  • Fig. 2 ein Querschnitt durch das Schlauchboot gemäß Fig. 1 in vergrößertem Maßstab und
  • Fig. 3 eine Variante als Teildarstellung einer Ansicht gemäß Fig. 2.
The invention is illustrated by the schematic representation of two exemplary embodiments in the drawing. In the drawing is:
  • 1 shows an inflatable boat according to the invention in a perspective view from behind onto the floor surface;
  • Fig. 2 is a cross section through the inflatable boat of FIG. 1 on an enlarged scale and
  • 3 shows a variant as a partial representation of a view according to FIG. 2.

Das gezeichnete Schlauchboot ist in seinen wesentlichen Teilen aus zwei den nutzbaren Innenraum einfassenden und durch einen den Innenraum nach unten abdichtenden flexiblen Bootsboden 4 untereinander verbundenen aufblasbaren Tragschläuchen 3 aufgebaut. Die Tragschläuche sind im Bugbereich des Bootes in an sich bekannter Weise zu einem stevenartig hochgezogenen Gebilde zusammengeführt und werden in Heckbereich in ebenfalls bekannter Weise von einem den Innenraum nach hinten abschließenden und gleichzeitig zum Aufnehmen eines nicht gezeichneten Außenbordmotors dienenden starren Heckbrett 5 in gegenseitigem Abstand gehalten. Zwischen den Tragschläuchen 3 befindet sich als unmittelbarer Abschluß des Bootsinnenraumes ein aus mehreren Teilen zusammengesetzter starrer Einlegeboden 6, gegen den sich ein in Längsrichtung durchlaufender aufblasbarer Kielschlauch 7 zum Spannen des flexiblen Bodens 4 abstützt. Die Schlauchkörper 3 und 7 wie auch der Boden 4 sind aus einem gummi- oder kunststoffbeschichteten Gewebe hergestellt.In its essential parts, the rubber dinghy shown is constructed from two inflatable support tubes 3 that enclose the usable interior space and are interconnected by a flexible boat bottom 4 that seals the interior space downward. The carrying hoses are brought together in the bow region of the boat in a manner known per se to form a steve-like structure and are kept at a mutual distance in the stern region in a likewise known manner by a rigid tail board 5 which closes the interior to the rear and at the same time serves to accommodate an outboard motor (not shown). Between the supporting hoses 3 there is a rigid shelf 6 composed of several parts, against which an inflatable keel tube 7 running in the longitudinal direction is supported for tensioning the flexible bottom 4 as a direct closure of the boat interior. The tube body 3 and 7 as well as the bottom 4 are made of a rubber or plastic coated fabric.

Die Zeichnung beschränkt sich allein auf die Darstellung der zum Verständnis der Erfindung wesentlichen Bootsteile. Von der Wiedergabe anderer Ausrüstungseinzelheiten, Beschlagelemente und Armaturen ist der Übersichtlichkeit halber abgesehen.The drawing is restricted solely to the representation of the boat parts essential for understanding the invention. For the sake of clarity, other equipment details, fitting elements and fittings have not been reproduced.

An der Unterseite der Tragschläuche 3 sind zusätzliche Schläuche 8 von im Einbauzustand etwa sichelförmiger Querschnittsgestalt aber wesentlich kleinerer Querschnittsfläche in senkrechter Ausrichtung zu diesen fest angebracht. Die als lialbschläuche, das heißt mit Halbkreisquerschnitt ebenfalls aus gasdicht imprägniertem Gewebe hergestellten zusätzlichen Schläuche sind mit den Tragschläuchen verklebt und nehmen im aufgeblasenen Gebrauchszustand die gezeichnete konkav gekrümmte Gestalt an. Ihre Länge ist der Länge der Bordwände entsprechend bemessen, und wie die Darstellung in Fig. 1 erkennen läßt, laufen sie über praktisch den gesamten geradlinigen Teil der Tragschläuche 3 durch. Der flexible Bootsboden 4 ist an ihrer Innenkante an die Tragschläuche angesetzt, so daß sie im Gebrauch des Schlauchbootes vollständig frei und voll wirksam sind.On the underside of the carrying hoses 3, additional hoses 8 of a cross-sectional shape which is roughly crescent in the installed state but of a substantially smaller cross-sectional area are fixedly attached in a vertical orientation to these. The additional hoses, which are also produced from gas-impregnated fabric with a semicircular cross section, are glued to the support hoses and assume the concave, curved shape shown in the inflated state of use. Their length is dimensioned according to the length of the side walls, and as can be seen in the illustration in FIG. 1, they run through practically the entire straight part of the carrying hoses 3. The flexible boat bottom 4 is on the inside edge of the Carrying hoses attached so that they are completely free and fully effective when using the inflatable boat.

Gemäß der Teildarstellung in Fig. 3 sind die zusätzlichen Schläuche von lose und auswechselbar in ihrerseits an den Tragschläuchen 3 befestigte formgebende Hüllen 18 eingelegten Schlauchkörpern 28 gebildet. Als weitere Variante ist in diesem Falle anstelle eines starren Einlegebodens über einem zugeordneten äußeren flexiblen Bootsboden ein an sich bekannter aufblasbarer Luftkammerboden 16 vorgesehen. An der Wirkung der Erfindung selbst ändert sich hierdurch nichts.According to the partial illustration in FIG. 3, the additional hoses are formed by loose and replaceable tubular bodies 28 inserted into form-forming sleeves 18 fastened in their turn to the support hoses 3. As a further variant, an inflatable air chamber floor 16 known per se is provided in this case instead of a rigid shelf above an associated outer flexible boat floor. This does not change the effect of the invention itself.
