Abstract

The universal-joint headpiece (1) of the forked-boom fastening for windsurfing sailboards has a tube bend (2) of aluminium or plastic for attaching the two booms of a forked boom, preferably by pushing them on or in. A one-piece fitting made of an elastic plastic is injection-moulded onto the tube bend (2); it consists of a sleeve-like collar (4) that can be slid onto the mast (3) of a windsurfing sailboard and connected rigidly to it, and a sheath section (5) that holds the tube bend (2), as well as a short web (6), connecting the collar (4) and the sheath section (5) to each other, that is constructed to bend and turn in all directions to a limited extent. <IMAGE>

Description

Gegenstand der Erfindung ist eine Gabelbaumbefestigung für Surfsegelbretter.The invention relates to a boom attachment for surfboard.

Die Verwendung von Trapezen bei Surfsegelbrettern birgt die Gefahr in sich, daß durch die bei Stürzen auftretenden großen Biege- und Torsionsmomente, die über den verdrehsicher am Mast befestigten Gabelbaum auf den Mast wirken, der Mast beschädigt wird und sogar brechen kann.The use of trapezoids on surf sail boards harbors the danger that by falling large bending and torsional moments that occur via the boom secured against rotation on the mast act on the mast, the mast is damaged and even can break.

Der Erfindung liegt die Aufgabe zugrunde, eine Gabelbaumbefestigung für Surfsegelbretter zu entwickeln, die bis zu einem gewissen Grade einen Ausgleich der auf den Gabelbaum wirkenden Kräfte ermöglicht, ohne die Manövrierfähigkeit des Brettes zu beeinträchtigen.The invention has for its object a To develop boom attachment for surfing sail boards, which to some extent compensates for the forces acting on the boom, without impair the maneuverability of the board.

Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale im Kennzeichen des Patentanspruches 1.This object is achieved by the Features in the characterizing part of patent claim 1.

Zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Appropriate configurations of the invention are Subject of the subclaims.

Die universalgelenkige Ausbildung der Gabelbaumbefestigung am Mast ermöglicht einen Ausgleich der auf den Gabelbaum wirkenden Biege- und Torsionsmomente auch bei hohen Beanspruchungen bis zu einem Grad, der eine Beschädigung des Mastes mit höchster Sicherheit ausschließt.The universal joint training of the Fork boom attachment to the mast enables compensation the bending and torsional moments acting on the boom even with high loads to a degree that damage to the mast with the greatest security excludes.

Die Erfindung ist nachstehend anhand von zwei in der Zeichnung dargestellten Ausführungsbeispielen im einzelnen erläutert. The invention is based on two in the Exemplary embodiments shown in the drawing individual explained.  

Die Fig. 1 und 2 zeigen zwei Ausführungsformen des erfindungsgemäßen Gabelbaumkopfstückes in der Draufsicht. Gleiche oder ähnliche Bauelemente der beiden Ausführungsbeispiele sind durch gleiche Bezugszeichen gekennzeichnet. Figs. 1 and 2 show two embodiments of the boom head piece according to the invention in plan view. Identical or similar components of the two exemplary embodiments are identified by the same reference symbols.

Das universalgelenkig ausgebildete Gabelbaumkopfstück (1) nach Fig. 1 weist einen Rohrbogen (2) aus Aluminium oder Kunststoff zum Anbringen, vorzugsweise Ein- oder Aufstecken, der beiden Bäume eines nicht dargestellten Gabelbaumes auf. An den Rohrbogen (2) ist ein einteiliges Anschlußstück aus einem elastischen Kunststoffmaterial, z.B. Polyurethan, angespritzt, das aus einer hülsenartigen, auf den Mast (3) eines Surfsegelbrettes aufschiebbaren und mit diesem fest verbindbaren Manschette (4) und einem den Rohrbogen (2) aufnehmenden Mantelteil (5) sowie einem kurzen Steg (6) besteht, der Manschette (4) und Mantelteil (5) miteinander verbindet und begrenzt allseitig biegbar und verdrehbar ausgebildet ist. Der Verbindungssteg (6), der einen Rechteckquerschnitt besitzt, ist radial zu der Manschette (4) angeordnet und liegt auf der Symmetrieachse (7-7) des Gabelbaumkopfstückes (1).The universal articulated formed boom head piece (1) according to Fig. 1 has a tube sheet (2) made of aluminum or plastic for attaching, preferably on or plugging, of the two trees of a tree fork, not shown. A one-piece connecting piece made of an elastic plastic material, for example polyurethane, is injection molded onto the pipe bend ( 2 ), which consists of a sleeve-like sleeve ( 4 ) that can be pushed onto the mast ( 3 ) of a surf sail board and is firmly connected to it, and a pipe bend ( 2 ) receiving jacket part ( 5 ) and a short web ( 6 ) which connects the sleeve ( 4 ) and jacket part ( 5 ) to each other and is designed to be flexible and rotatable on all sides. The connecting web (6) having a rectangular cross section, is disposed radially of the sleeve (4) and lies on the axis of symmetry (7 - 7) of the boom head piece (1).

Bei dem Gabelbaumkopfstück (8) nach Fig. 2 sind Manschette (4) und Mantelteil (5) durch zwei begrenzt allseitig biegbare und verdrehbare Stege (9, 10) miteinander verbunden, die klappsymmetrisch und spitzwinklig zur Symmetrieachse (7-7) des Kopfbogenstückes (8) angeordnet sind. . In the boom head piece (8) of Figure 2 are cuff (4) and casing part (5) by two bounded on all sides bendable and twistable webs (9, 10) connected together, the mirror-symmetrical and at an acute angle to the symmetry axis (7 - 7) of the head sheet piece ( 8 ) are arranged.
