Abstract

Wishbone boom mounting for sailboards with a wishbone head section of a synthetic resin, integrally molded onto a curved pipe section of aluminum or synthetic resin for attaching the two spars of a wishbone boom, and a jacket section accommodating the curved pipe section. A collar is connected to the jacket section by at least one web and is placeable on the mast. A locking element is articulated to this collar and receives the mast. A quick-action closure closes and opens the locking element in order to mount the head section to the mast or to detach the head section from the mast. A hinged cover (10) is molded onto the collar (6) of the wishbone head section (1) by a thin flexible hinge (11) and is curved to match the mast (5). A clamping lever (12) is articulated to the collar (6) for tightening and releasing a rope piece (13) forming a loop (14), one end of this rope piece being attached to the clamping lever (12) and the other end to the collar (6) in the region of the thin flexible hinge (11). The loop (14) of this rope piece is tensionable for attaching the wishbone head section (1) to the mast (5) by the clamping lever (12) by an extension (20) on the collar (6) opposite the closing rim (19) of the hinged cover (10) and by guides (22, 23) on the outside of the hinged cover (10).

Description

Gegenstand der Erfindung ist eine Gabelbaumbefestigung für Surfsegelbretter mit einem Gabelbaumkopfstück aus Kunststoff, das an einen Rohrbogen aus Aluminium oder Kunststoff zum Anbringen der beiden Holme eines Gabelbaumes einteilig angespritzt ist und ein den Rohrbogen aufnehmendes Mantelteil, eine mit diesem durch mindestens einen Steg verbundene, auf den Mast aufschiebbare Manschette, an der ein dem Mast angepaßtes Verschlußelement angelenkt ist, und einen Schnellspannverschluß zum Schließen und Öffnen des Verschlußelementes zur Befestigung des Kopfstückes am bzw. Lösen desselben vom Mast aufweist.The invention relates to a boom attachment for surfing sail boards with a boom head piece made of plastic, which is integrally molded on a pipe bend made of aluminum or plastic for attaching the two spars of a boom and a jacket part receiving the pipe bend, one connected to it by at least one web, on the Mast slide-on sleeve, on which a locking element adapted to the mast is articulated, and has a quick-action closure for closing and opening the locking element for fastening the head piece to or releasing the same from the mast.

Bei einer derartigen durch das DE-GM G 84 18 494.9 bekannten Gabelbaumbefestigung besteht der Verschluß zur Befestigung des Gabelbaumkopfstückes auf dem Mast aus einer halbkreisförmigen Andruckplatte, die auf der einen Seite durch eine Tampenschlaufe mit dem Gabelbaum beweglich verbunden ist und auf der anderen Seite einen Ansatz aufweist, in den zur Befestigung des Gabelbaumkopfstückes auf dem Mast eine durch einen weiteren Tampen gebildete Schlaufe eingehängt wird, deren eines Ende nach einer mehr als 90 gradigen Umlenkung durch eine in das Kopfstück eingeschraubte Öse mit dem an dem Kopfstück angelenkten Spannhebel eines Schnellspannverschlusses verbunden ist und deren anderes Ende nach einer Umlenkung von mehr als 90° durch eine weitere in das Kopfstück eingeschraubte Öse in einer an dem Gabelbaum angebrachten Curry-Klemme befestigt wird. Zum Verbinden. von Mast und Gabelbaum wird die Tampenschlaufe in die Andruckplatte eingehängt und der Spannhebel umgelegt, wodurch die Andruckplatte des Gabelbaumkopfstückes an den Mast angepreßt wird.In such a boom mounting known from DE-GM G 84 18 494.9, the closure for attaching the boom head piece on the mast consists of a semicircular pressure plate which is movably connected on one side by a tamp loop with the boom and on the other side an approach has, in which to attach the boom head piece on the mast a loop formed by another rope is hooked, one end of which is connected after a more than 90 degree deflection by an eyelet screwed into the head piece to the clamping lever of a quick-action fastener articulated on the head piece, and the other end of which is fixed after a deflection of more than 90 ° by a further eyelet screwed into the head piece in a curry clamp attached to the boom. To connect. from the mast and boom, the pad loop is hooked into the pressure plate and the tension lever is turned, whereby the pressure plate of the boom head piece is pressed against the mast.

Diese bekannte Gabelbaumbefestigung ist sehr aufwendig. Ferner besteht die Gefahr, daß beim Lösen und Befestigen des Gabelbaumes vom bzw. am Mast das Segel in dem Verschluß des Gabelbaumkopfstückes hängenbleibt und beschädigt wird.This well-known boom mounting is very complex. Furthermore, there is a risk that when detaching and attaching the boom from or to the mast, the sail will get caught in the closure of the boom head and be damaged.
