Abstract

The sail, partic. for a windsurfer. is of conventional triangular shape. The sail has a pocket (7) running the length of the luff, into which the mast fits. To reduce the turbulence caused by its sewn edge, instead of being a close fit around the mast all the way the pocket has a cross-section several times that of the mast at its mouth and tapers to a close fit at the tip. A hole (10) near the tip ensures free drainage of any water trapped in the pocket.

Description

Beschreibungdescription

Die vorliegende Erfindung bezieht sich auf Segel, insbesondere für Segelbretter, mit einer vorliekseitigen Masttasche. Die Masttasche dieses Segels ist auf den Durchmesser des zugehörigen Mastes zugeschnitten, d.h.The present invention relates to sails, particularly for Sailboards, with a mast pocket on the luff side. The mast pocket of this sail is cut to the diameter of the associated mast, i.e.

ihr Quergchnttt ist nur unwesentlich größer als der des Mastes Hierdurch ergibt sich der Nachteil, daß am Übergang von der Masttasche zur anschließenden Segelfläche eine mehr oder weniger scharfkantige Abwinkelung vorhanden ist. Diese wirkt sich strömungsteehnisch ungünstig aus Zweck der vorliegenden Erfindung ist daher die Verbesserung des Segelprofils derartiger Segel.its cross section is only slightly larger than that of the mast there is the disadvantage that at the transition from the mast pocket to the subsequent Sail area has a more or less sharp-edged bend. These has an unfavorable aerodynamic effect. The purpose of the present invention is hence the improvement of the sail profile of such sails.

Erfindungsgemäß ist dies dadurch zu erreichen, daß der Umfang der Masttasche am offenen unterliekseitigen Ende ein Mehrfaches deg Umfangs des zugehörigen Mastes im entsprechenden Querschnittsbereieh ausmacht. Eine derartige Vergrößerung der Masttasche führt zu einem flügaigen Ubergang zwischen der Masttasche und der ansehljeßenden Segelfläehe. Diese Ausbildung bringt noch einen weiteren Vorteil mit sich, der darin besteht, daß aih der Mast viel sehneller und einfacher in die Masttasche einführen lässt als bisher bei den bekannten Segeln. So ist es praktisch kaum noch möglich, daß sich die Mastspitze beim Einbringen an der oberen Kante des Lochs in der Masttasche zum Durchführen eines Befestigunggtampens für den Gabelbaum verhakt.According to the invention this can be achieved in that the scope of Mast pocket at the open end on the lower leech side is a multiple of the circumference of the associated Mast in the corresponding cross-sectional area. Such an enlargement the mast pocket leads to a smooth transition between the mast pocket and the attached sail area. This training brings another advantage with itself, which consists in the fact that the mast is much easier and easier to fit into the Mast pocket can be introduced than before with the known sails. It is hardly practically that way anymore possible that the mast tip is at the top of the hole in hooked into the mast pocket to carry out a fastening rope for the boom.

Insbesondere, wenn es sich um dreieckige Segel handelt, hat es sich als zweekmäßig erwiesen, daß die Masttasche sich zum Kopf des Segels hin verengt.Especially when it comes to triangular sails, it has to be it has been proven that the mast pocket narrows towards the head of the sail.

Da in die vergrößerte Masttasche bei im Wasser liegenden Segel aueh mehr Wasser eintreten kann, ist es vorteilhaft, wenn die Masttasehe wenigstens am kopfseitigen Ende eine Lenzöffnung besitzt, so daß das Segel verhältnismäßig leieht wieder aus dem Wasser gezogen werden kann.Because in the enlarged mast pocket when the sails are in the water more water can enter, it is advantageous if the fattening marriage at least on head end has a bilge opening, so that the sail is relatively easy can be pulled out of the water again.

Im folgenden ist anhand der beiliegenden Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstandes ausführltch besGhriebeno Es zeigen Fig. 1 ein komplettes Segelbrett in Seitenansicht, und Fig. 2 einen Schnitt durch das Segel nach der linie IIII der Fig. t.The following is an exemplary embodiment with reference to the accompanying drawing of the subject matter of the invention in detail. Fig. 1 shows a complete A side view of the sailboard, and FIG. 2 shows a section through the sail along the line IIII of Fig. T.

Das in Fig. 1 dargestellte Segelbrett umfaßt einen Brettkorper,1, der ein Schwert 2 und eine Finne 3 trägt.The sailing board shown in Fig. 1 comprises a board body, 1, who carries a sword 2 and a fin 3.

Auf dem Brettkörper ist mittels eines Mastfußes 4 der Mast 5 befestigt. Der Mast ist drehbar und nach allen Seiten schwenkbar, wozu der Mastfuß beispielsweise ein entsprechendes Gelenk umfaßt.On the board body is by means of a mast foot 4 the Mast 5 attached. The mast can be rotated and swiveled in all directions, including the Mast foot includes, for example, a corresponding joint.

Der Mast 5 trägt ein Segel 6, wozu er in eine vorliekseitige Masttasche 7 eingesteckt ist. Weiter trägt der Mast noch einen Gabelbaum 8. Zum Durchführen eines nicht dargestellten Befestigungstampens für den Gabelbaum besitzt die Masttasche ein Loch 9.The mast 5 carries a sail 6, for which purpose it is placed in a mast pocket on the luff side 7 is plugged in. The mast also carries a boom 8. To guide it through the mast pocket has a fastening ram, not shown, for the boom a hole 9.

Erfindungsgemäß macht der Umfang der Masttasche 7 am offenen unterliekseitigen Ende ein Mehrfaches des Umfangs des Mastes 5 aus. Da bei dem dargestellten Ausführungobeispiel das Segel 6 die Form eines Dreiecks besitzt, verengt sieh die Masttasche 7 zum Kopf des Segels hin Wie Fig. 2 erkennen läßt, führt die Vergrößerung der Masttasche 7 zu einem optimalen Segelprofil.According to the invention makes the scope of the mast pocket 7 on the open lower leech side At the end of a multiple of the circumference of the mast 5. Since in the illustrated embodiment the sail 6 has the shape of a triangle, see the mast pocket 7 narrows towards the head of the sail as shown in FIG. 2, the enlargement of the mast pocket 7 leads to an optimal sail profile.

Am kopfseitigen Ende besitzt die Masttasche 7 noch eine Lenzöffnung 10, aus der Wasser ablaufen kann, wenn dieses bei im Wasser liegenden Segel in die Masttasche eingetreten ist.At the head end, the mast pocket 7 also has a bilge opening 10, from which water can run off if this is in the Mast pocket has entered.
