Abstract

The invention is intended to provide a highly aerodynamically effective sail. Sails with laths to stabilise the shape and highly aerodynamically effective split sails are known. The invention combines the advantages of both designs by providing a split sail consisting of a foresail and a mainsail with a foresail consisting of segments and with sail laths in the region of the gaps between the foresail components. The novel sail is intended especially for surfboards.

Description

Beschreibung:Description:
Segel für windangetriebene Fahrzeuge.Sails for wind powered vehicles.
Die Erfindung betrifft ein Segel für windangetriebene Fahrzeuge insbesondere Surfbretter, gebildet aus wenigstens einer zwischen einer Vorderkante und ei¬ ner Hinterkante ausgestreckten Gewebe- oder Folienbahn.The invention relates to a sail for wind-powered vehicles, in particular surfboards, formed from at least one fabric or film web stretched out between a leading edge and a trailing edge.
Die aerodynamische Wirksamkeit von einfachen Segeln, die nur aus aufge¬ spannten Gewebe- oder Folienbahnen bestehen, kann durch eine Reihe von Maßnahmen verbessert werden.The aerodynamic efficiency of simple sails that stretched only from discontinued ¬ tissue or foil conveyors, can be improved by a number of measures.
Es ist bekannt, daß durch Segellatten, von denen zumindest einige sich von der Vorderkante bis zur Hinterkante des Segels erstrecken, das aerodynami¬ sche Profil eines Segels und insbesondere das eines Surfsegels stabilisiert werden kann. Aufgrund der Segel latten wird die Profiltiefe des Segels durch wechselnden Winddruck nur noch wenig verändert. Hierdurch erhöht sich seine Druckpunktstabilität.It is known that battens, at least some of which extend from the front edge to the rear edge of the sail, can be used to stabilize the aerodynamic profile of a sail and in particular that of a surf sail. Due to the battens, the profile depth of the sail is only slightly changed by changing wind pressure. This increases its pressure point stability.
Aus der OS DE 4229443 AI ist ein Spaltsegel bekannt, in seiner Wirkung ver¬ gleichbar mit einem Spaltflügel aus dem Flugzeugbau. Das Spaltsegel besteht aus einem Vorsegel und einem Hauptsegel. Das Vorsegel ist in einem Winkel¬ bereich um die Vorderkante des Segels schwenkbar, so daß zwischen der Hinterkante des Vorsegels und der Vorderkante des Hauptsegels ein Spalt entsteht. Der Winkelbereich wird vorgegeben durch Abspannungen, die das Vorsegel umfassen und am Hauptsegel befestigt sind. Die im Patentanspruch 1 angegebene Erfindung macht sich zur Aufgage, in ei¬ nem neuartigen Segel, die Merkmale eines Segels mit Segellatten, mit den Merkmalen eines Spaltsegels geeignet zu verbinden, so daß ein aerodynamisch vorteilhaftes Segel entsteht.A slotted sail is known from OS DE 4229443 AI, the effect of which is comparable to that of a slotted wing from aircraft construction. The split sail consists of a headsail and a main sail. The foresail can be pivoted in an angular range around the front edge of the sail, so that a gap is formed between the rear edge of the foresail and the front edge of the main sail. The angular range is specified by bracing that includes the headsail and is attached to the main sail. The specified in claim 1. invention makes for Aufgage, in egg ¬ nem novel sail, the features of a sail with battens, with the features of a sail gap suitable to be connected, so that an aerodynamically advantageous sail is produced.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das neuartige Segel als Spaltsegel gemäß OS DE 4229443 AI ausgeführt ist. bestehend aus Vorse¬ gel und Hauptsegel, mit einem aus Vorsegel Segmenten aufgebauten Vorsegel, und Segellatten, die entlang der Trennungslücke zwischen den Segmenten des Vorsegels an die Vorderkante des Segels heranreichen.The object is achieved in that the novel sail is designed as a slotted sail according to OS DE 4229443 AI. Consisting of foresail and main sail, with a foresail made up of foresail segments, and sail battens, which reach the front edge of the sail along the gap between the segments of the foresail.
Durch den erfindungsgemäßen Aufbau des Vorsegels aus Vorsegelsegmente, wobei jedes Vorsegelsegment die wesentlichen Merkmale des Vorsegels aus OS DE 4229443 AI aufweist, kann das Vorsegel an den bis zur Vorderkante des Segels reichenden Segellatten vorbeischwenken.Due to the construction according to the invention of the head sail from head sail segments, each head sail segment having the essential characteristics of the head sail from OS DE 4229443 AI, the head sail can swing past the battens reaching to the front edge of the sail.
Im Bereich der Vorderkante des Segels können die Vorsegelsegmente mitei¬ nander verbunden sein.The foresail segments can be connected to one another in the region of the front edge of the sail.
Vorteilhaft wird die Trennungslücke zwischen den Vorsegelelsegmenten durch ein Abspannband aus Gewebe oder Folie bedeckt. Das Abspannband ist in der Nähe der Vorderkante des Hauptsegels mit dem Hauptsegel verbunden, wird um die Vorderkante des Segels gelegt, zum Hauptsegel zurückgeführt und dort wieder befestigt. Die Breite des Abspannbandes ist geeignet gewählt, so daß das Abspannband Schwenkbewegungen der Vorsegelsegmente um die Vor¬ derkante des Segels nicht behindert.The gap between the foresail gel segments is advantageously covered by a guy tape made of fabric or film. The guy tape is attached to the main sail near the leading edge of the main sail, is placed around the leading edge of the sail, returned to the main sail, and reattached there. The width of the anchoring strip is appropriately chosen so that the bracing band pivotal movements of the headsail segments hampered by the pre ¬ of the sail not derkante.
Besonders vorteilhaft, da aerodynamisch günstig, wird die Vorderkante des Se¬ gels in abgerundeter Form ausgeführt. Die Vorderkante des Segels kann, wie bei Surfsegeln üblich, ein Mast sein. In diesem Fall stützen sich vorteilhaft die zur Vorderkante des Segels führenden Segellatten am Mast ab. Ein Ausführungsbeispiel der Erfindung in Form eines Surfsegels ist in Fig.l und Fig.2 dargestellt. Das Surfsegel in Fig.l besteht aus einem Vorsegel (1) und einem Hauptsegel (2). Das Vorsegel setzt sich aus 6 Vorsegelsegmente (3) zusammen. In einem der Vorsegelsegmente (3) ist die Öffnung (4) für den Ga¬ belbaum eingearbeitet. Insgesamt 5 Abspannbänder (5) werden um den Mast (6) gelegt und sind am Hauptsegel (2) befestigt. Die Segellatten (7) reichen von der Vorderkante bis zur Hinterkante des Surfsegels.Particularly advantageous since aerodynamically favorable, the leading edge of the Se ¬ gels is executed in a rounded shape. The leading edge of the sail can, as is usual with surf sails, be a mast. In this case, the battens leading to the front edge of the sail are advantageously supported on the mast. An embodiment of the invention in the form of a surf sail is shown in Fig.l and Fig.2. The surf sail in Fig.l consists of a headsail (1) and a main sail (2). The headsail consists of 6 headsail segments (3). In one of the headsail segments (3) the opening (4) for the Ga ¬ wiring harness is incorporated. A total of 5 guy straps (5) are placed around the mast (6) and attached to the main sail (2). The battens (7) extend from the front edge to the rear edge of the surf sail.
In Fig.2 ist ein Teil der Vorderkante des Surfsegels dargestellt. Zwei Vorse¬ gelsegmente (3) sind teilweise abgebildet. Die Trennungslücke zwischen den Vorsegelsegmenten (3) wird durch ein Abspannband (5) abgedeckt. Das Ab¬ spannband (5) ist um die Vorderkante des Segels, in diesem Fall einen Mast (6), gelegt, und am Hauptsegel (2) befestigt. Die Segellatte (7) stützt sich über einen Adapter (8) am Mast (6) ab. Die Abspannung (9) und der Abstandshalter (10) begrenzen den Schwenkbereich des Vorsegelsegments (3). A part of the front edge of the surf sail is shown in FIG. Two Vorse ¬ gel segments (3) are partially shown. The gap between the headsail segments (3) is covered by a guy tape (5). From the ¬ clamping band (5) is attached to the leading edge of the sail, in this case, a mast (6), down and to the mainsail (2). The batten (7) is supported by an adapter (8) on the mast (6). The guying (9) and the spacer (10) limit the swivel range of the headsail segment (3).
