Abstract

A sail with a tubular portion is pulled over a mast and/or a stay of a sailing vessel. The tubular portion is inflatable through a sail mouth opening at the fore leech thus forming an air envelope of the sail due to the relative wind effects. A plurality of telescoping contour sleeves formed of a lightweight, floating, elastic material are arranged in the tubular portion and sheath the mast and/or stay as well as selected portions of the rigging. The formation of an air envelope from a part of the sail and the use of rotatable streamlined contour sleeves inhibit complete heeling over of the sailing vessel and simplify the erecting of surfboards and sailboats. The telescoping arrangement of the contour sleeves permits an alteration of the sail surface and the sheathing of the rigging further decreases the wind resistance leading to an increased speed capability without need for greater inclination of the vessel. Thus the sails are better able to utilize the wind energy.

Description

Die Erfindung betrifft die Bildung einer Lufthülle und Formteile zur Profilierung von Segeln gemäß dem Oberbegriff von Anspruch 1.The invention relates to the formation of an air envelope and molded parts for profiling sails according to the preamble of claim 1.

Beim Bau der gebräuchlichen Segelfahrzeuge gehen alle Bestrebungen dahin, eine Profilverbesserung der Segel bei gleichzeitiger Widerstandsverminderung der Takelage unter der Voraussetzung zu erreichen, daß das Fahrzeug den atmosphärischen Wind von zwei Seiten ausnutzen muß.When building the usual sailing vehicles, every effort is made to improve the profile of the sails while at the same time reducing the resistance of the rigging, provided that the vehicle has to take advantage of the atmospheric wind from two sides.

Es ist bekannt zur Erfüllung dieser Erfordernisse einen Profilmast mit einem über die übliche Stromlinienform des festen Mastes hinaus nach achtern verlängerten Mastprofil, welcher meist drehbar angeordnet ist und auch mit einem halbstarren Segel oder einem Lattensegel gefahren werden kann, zu verwenden ("Segler Lexikon" Joachim Schult Verlag Klasing & CO GMBH, Bielefeld 1978 2. Auflage Seite 311). Dabei haben die Starrsegelteile Stromlinienform mitbeidseitig konkaven und unveränderlichen Wölbungen. Starrsegel haben sich jedoch nicht durchsetzen können, weil ihnen die geringe aber wichtige Verwindung nicht gegeben werden kann, welche dem Segel auf jeder Höhe über dem Wasser den richtigen Anstellwinkel gibt, der dem Windgradienten des atmosphärischen Windes in zunehmender Höhe über dem Wasserspiegel entspricht (vgl. "Das Segel" Jeremy Howard-Williams Deutsche Ausgabe Verlag Delius Klasing & Co. Bielefeld Berlin 1969).To meet these requirements, it is known to use a profiled mast with a mast profile which is extended aft beyond the usual streamlined shape of the fixed mast and which is usually rotatably arranged and can also be driven with a semi-rigid sail or a slat sail ("Segler Lexikon" Joachim Schult Verlag Klasing & CO GMBH, Bielefeld 1978 2nd edition page 311). The rigid sail parts have a streamlined shape with concave and unchangeable curvatures on both sides. Rigid sails have not been able to prevail, however, because they cannot be given the slight but important torsion that gives the sail the correct angle of attack at any height above the water, which corresponds to the wind gradient of the atmospheric wind at increasing heights above the water level (cf. "Das Segel" Jeremy Howard-Williams German Edition Verlag Delius Klasing & Co. Bielefeld Berlin 1969).

Der Gedanke, das Segel mit Mast und Windanschnittskante flügelförmig auszubilden, ist schon 1922 in der DE-C-384 075 offenbart worden. Segeln läßt sich's damit woht sehr gut; aber schon um ein solches Segel bei mäßiger Brise zu setzen, müssen mehrere Leute anfassen, da die Anordnung zu umständlich ist - ganz von den Schwierigkeiten zu schweigen, wenn eine Böe einsetzt -.The idea of making the sail wing-shaped with a mast and a leading edge was already disclosed in DE-C-384 075 in 1922. It is very easy to sail with it; but in order to set such a sail in a moderate breeze, several people have to touch it, because the arrangement is too cumbersome - not to mention the difficulties when a gust sets in -.

Die Aufgabe, eine Profilverbesserung bei gleichzeitiger Verminderung des Widerstandes der Takelage eines Schiffes herbeizuführen, kann nach der DE-A-2356 426 nicht als gelöst angesehen werden, nach der mehrere Leichtmetallsegel teleskopartig in das Untersegel einführbar sind. Dazu wäre die nicht dargelegte Takelage zu kompliziert, und zur Verkleinerung der Segelfläche nach Wegnehmen der oberen Einzelstücke kann das letzte Tragflächensegel mit den darin angeordneten Teilstücken - das Großsegel - gar nicht weggenommen werden.According to DE-A-2356 426, the task of improving the profile while simultaneously reducing the resistance of the rigging of a ship cannot be regarded as solved, according to which several light metal sails can be telescopically inserted into the lower sail. The rigging not shown would be too complicated for this, and to reduce the sail area after removing the upper individual pieces, the last wing sail with the sections arranged therein - the mainsail - cannot be removed at all.

Die ferner in den Figuren 1 und 2 der FR-A-1 464 877 dargestellten Profilmasten lassen sich nicht drehen, wodurch der Nutzen eines solchen Riggs stark gemindert ist. Da die Windanschnittskante nach Figur 3 nicht starr ist, wird der Wind das Segeltuch einbeulen und somit einen schlechten Stand zeigen. Kopflastigkeit ist vorhanden. Ein Segelmacher wird kaum ein aerodynamisches Profil in solch ein Segel einarbeiten können.The profile masts also shown in FIGS. 1 and 2 of FR-A-1 464 877 cannot be rotated, as a result of which the use of such a rig is greatly reduced. Since the wind gating edge according to FIG. 3 is not rigid, the wind will dent the canvas and thus show a poor stance. Head heaviness is present. A sail maker will hardly be able to incorporate an aerodynamic profile into such a sail.

Bekannt sind ferner das "Rigg für ein Segelbrett" (deutsche Patentschrift Nr. 1 914604) sowie "A wind-propelled vehicle" (Australische Patentschrift No.46 552/79). Beide Schutzrechte betreffen in wesentlichen Teilen die Befestigung des Mastes auf einem Segelbrett sowie die Verbindung zwischen dem Mast und zwei nach außen gekrümmten Großbäumen. Nach der deutschen Patentschrift Nr. 1 914 604 ist es ferner bekannt, das Vorliek eines Segels für ein Segelbrett als Saum auszubilden, in den der Mast eingeführt wird. Es hat sich jedoch gezeigt, daß eine grundlegende Profilverbesserung des Segels nicht erreicht wurde, solange der Mast die Windanschnittskante des Großsegels bleibt.Also known are the "rig for a sailing board" (German patent no. 1 914604) and "A wind-propelled vehicle" (Australian patent no.46 552/79). Both property rights essentially concern the attachment of the mast to a sailing board as well as the connection between the mast and two outwardly curved large trees. According to German Patent No. 1 914 604 it is also known to form the luff of a sail for a sail board as a seam into which the mast is inserted. However, it has been shown that a fundamental improvement in the profile of the sail has not been achieved as long as the mast remains the leading edge of the mainsail.

Der Erfindung liegt die Aufgabe zugrunde, den Mast bzw. das Stag in das Segel aufzunehmen und mittels leichter Profilformen und Aufüllen einer Profilhülle durch den Fahrtwind die für Segelfahrzeuge günstige Profilierung zu schaffen. Wenn dazu noch auf größeren Booten die Takelage beispielsweise dadurch verändert wird, daß der Mast von mittschiffs seitwärts als Spreizmast an die Bordwände versetzt wird, werden durch Weglassen jeglicher Mastverstrebungen die besten Vortriebswerte besonders auf raumen Segelkursen erzielt.The invention has for its object to incorporate the mast or the stay in the sail and to create the profile that is favorable for sailing vehicles by means of slight profile shapes and filling up a profile envelope by the airstream. If the rigging of larger boats is changed, for example, by moving the mast sideways from midships as an expansion mast to the side walls, the best propulsion values are achieved, especially on clear sailing courses, by omitting any mast struts.

Die Lösung dieser Aufgabe ist in Anspruch 1 gekennzeichnet. Die Erfindung zeichnet sich dadurch aus, daß durch die Verkleidung von Mast und Stag - gegebenenfalls auch die Ummantelung von runden Spreizmasten - mit leichten beweglichen und stromlinienförmigen Profilteilen der Windwiderstand bis auf den siebenten Teil herabgesetzt werden kann. Es wird dadurch insbesondere eine Geschwindigkeitserhöhung ohne eine bisher stärkere Schräglage des Bootesmithin die beste Windausnutzung der Segel - erzielt.The solution to this problem is characterized in claim 1. The invention is characterized in that the wind resistance can be reduced to the seventh part by covering the mast and stay - possibly also the casing of round spreading masts - with light, movable and streamlined profile parts. In particular, an increase in speed is achieved without a previously more inclined position of the boat with the best wind utilization of the sails.

dar. Die in Figur 1 dargestellte Takelage besteht aus einem Mast 2, über den die erfindungsgemäß teleskopartig mit einander verbundenen Profilhülsen 4 mit den Grundplatten 5 gezogen sind. Diese sind im einzelnen in Figuren 3 und 4 dargestellt. An dem Mast 2 ist das Segel 1 zwischen dem Doppelbaum 8 gehißt, indem es mit seinem schlauchförmigen Teil über Mast und Profilhülsen gezogen ist. Dies wird durch Öffnen der Reißverschlüsse 18, 19 erleichtert, welche sich in dem schlauchförmigen Teil des Segels befinden und von unten nach oben zu öffnen sind.The rigging shown in FIG. 1 consists of a mast 2, over which the profile sleeves 4, which are telescopically connected to one another with the base plates 5, are drawn. These are shown in detail in FIGS. 3 and 4. On the mast 2, the sail 1 is hoisted between the double boom 8 by pulling its tubular part over the mast and profile sleeves. This is facilitated by opening the zippers 18, 19, which are located in the tubular part of the sail and can be opened from the bottom up.

Die in den Lattentaschen 30 befindlichen Segellatten 29 erstrecken sich durch den schlauchförmigen Teil des Segels zu den Verlängerungen 28 der Grundplatten 5, in denen sie nach oben und unten beweglich - mittels Bolzen befestigt sind - wie insbesondere aus Figur 2 ersichtlich -.The battens 29 located in the batten pockets 30 extend through the tubular part of the sail to the extensions 28 of the base plates 5, in which they can be moved up and down - are fastened by means of bolts - as can be seen in particular in FIG. 2.

Während Figuren 1 - 4 eine neuartige Takelage bei Mastführung zeigen, sind aus Figuren 5 bis 7 entsprechende Teile bei Stagführung ersichtlich. Die Profilhülsen 21 sind bei dieser Ausführungsform rund; die Grundplatten 22 können entsprechend Figur 6 oval oder wie in Figur 7 rund sein. Sie haben einzelne Bohrungen zur Führung von Stag 3, Teleskopleine 6 und Niederholer 7. In jedem Fall weisen die Profilhülsen in Höhe des Doppelbaumes 8 den größten Durchmesser auf. Die Grundplatten sind mit den Hülsen, welche vorzugsweise aus Schaumstoff bestehen, verklebt. Das Zusammenschieben erfolgt mittels der Teleskopleine 6, welche ober- und unterhalb jeder Grundplatte knoten aufweist. Figuren 4 und 6 zeigen einzelne Hülsen 4 und 21, welche in Richtung Achterliek Ausschnitte 31 aufweisen, welche die Lattenhalterung 28 der Grundplatten 5, 22 beim Zusammenschieben der Profilhülsen 4, 21 führen.While FIGS. 1-4 show a new type of rigging in mast guidance, corresponding parts in stage guidance are shown in FIGS. 5 to 7. The profile sleeves 21 are round in this embodiment; 6, the base plates 22 can be oval or round as in FIG. They have individual bores for guiding stage 3, telescopic line 6 and downhaul 7. In any case, the profile sleeves at the height of the double boom 8 have the largest diameter. The base plates are glued to the sleeves, which are preferably made of foam. The pushing together takes place by means of the telescopic line 6, which has knots above and below each base plate. FIGS. 4 and 6 show individual sleeves 4 and 21, which have cutouts 31 in the direction of the leech, which guide the slat holder 28 of the base plates 5, 22 when the profile sleeves 4, 21 are pushed together.

Figur 10 zeigt die Verbindung zwischen Mast 2 und Doppelbaum 8 mittels der rostfreien klammer 9, welche sich durch eine von mehreren Öffnungen im Segel 1, den sogenannten Segelmund 35, erstreckt, den Mast 2 umfaßt und mit beiden Enden am Doppelbaum 8 befestigt ist. Die klammer wird mittels eines verschraubbaren Bolzens entsprechend Figur 11 eingesetzt. Der verachiebbare Ring 12 mit der Bohrung 13 dient zur Führung der Turbulenzleine 14. Figuren 5 und 12 zeigen die Verbindung von Doppelbaum 8 mit Stag 3, welches an der Unterseite der rostfreien Platte 11 eingeschäkelt ist. Die rostfreie Platte 11 ragt durch eine Öffnung 35 des Segels 1 hindurch und besitzt Bohrungen zur Führung des Stages 3, der Teleskopleine 6 sowie Auf- und Niederholer. Das in Figur 13 dargestellte Segel mit Stagführung ist jeweils zwischen dem Segelschuh 24 und dem Segelhut 25 gehißt. Der Segelhut ist in Figur 8 in Seitenansicht, in Figur 9 in Draufsicht dargestellt. Er besitzt in der Mitte eine Bohrung 26 zur Aufnahme eines Warbels 27, welcher daa Segelfall aufnimmt. In Verlängerung des Warbels 27 nach innen sind die Teleskopleine 6 und ein Niederholer 7 angebracht.Figure 10 shows the connection between mast 2 and double boom 8 by means of the stainless clamp 9, which extends through one of several openings in the sail 1, the so-called sail mouth 35, includes the mast 2 and is attached to the double boom 8 with both ends. The clamp is used by means of a screwable bolt according to Figure 11. The displaceable ring 12 with the bore 13 serves to guide the turbulence line 14. FIGS. 5 and 12 show the connection of the double boom 8 to the stage 3, which is hooked onto the underside of the stainless plate 11. The stainless plate 11 protrudes through an opening 35 of the sail 1 and has bores for guiding the stage 3, the telescopic line 6 as well as the coiler and retractor. The sail with stage guide shown in Figure 13 is hoisted between the sailing shoe 24 and the sailing hat 25. The sailing hat is shown in Figure 8 in side view, in Figure 9 in plan view. It has a bore 26 in the middle for receiving a warble 27, which receives the sail case. In an extension of the warble 27 to the inside, the telescopic line 6 and a downhaul 7 are attached.
