Description

Die Erfindung betrifft einen längenverstellbaren Gabelbaum für Surfbretter, mit zwei durch ein Gabelbaumkopfstück verbundenen Hauptholmen und zwei in diesen teleskopartig verstellbaren Verlängerungsholmen, die achterliekseitig durch ein elastisches Gabelbaumendstück miteinander verbunden sind, sowie Vorrichtungen zum Verriegeln der Holme bei der entsprechend der Segelgröße eingestellten Länge des Gabelbaumes mit je einer mit den Enden der Hauptholme fest verbundenen Innenhülse, die über das Ende des Hauptholms axial vorstehende Rastzungen mit radial nach außen vorragenden Klemmabschnitten aufweist, wobei an den Enden der Rastzungen in Umfangsrichtung verlaufende, radial nach innen vorstehende Rastringsegmente angeformt sind, und mit einer mit der Innenhülse verriegelbaren, als Klemmhülse ausgebildeten Außenhülse, durch die beim Aufschieben auf die Innenhülse die an dieser angeordneten Rastzungen zusammengedrückt werden, so daß die an den Rastzungen angeformten Rastringsegmente in mit Abstand auf den Verlängerungsholmen angeordnete Umfangsrillen einrasten.The invention relates to a length-adjustable boom for surfboards, with two main spars connected by a boom headpiece and two extension spars which are telescopically adjustable in these and which are connected to one another on the left side by an elastic boom end piece, and to devices for locking the spars at the length of the boom set according to the sail size one each with the ends of the main spars firmly connected inner sleeve, which has axially projecting locking tongues with radially outwardly projecting clamping sections over the end of the main spar, with radially inwardly projecting locking ring segments being formed on the ends of the locking tongues, and with one lockable of the inner sleeve, designed as a clamping sleeve, by which the locking tongues arranged on the inner sleeve are pressed together when pushed onto the inner sleeve, so that the locking ring formed on the locking tongues Snap the segments into circumferential grooves spaced on the extension bars.

Bei einem durch die EP 0317661 A1 bekannten längenverstellbaren Gabelbaum dieser Art werden zur Verriegelung der Hauptholme mit den Verlängerungsholmen die mit einem Innengewinde versehenen Außenhülsen auf die ein entsprechendes Außengewinde aufweisenden Innenhülsen aufgeschraubt. Die heute bei Surfbrettern überwiegend zum Einsatz kommenden Sitztrapeze bewirken eine starke Torsionsbeanspruchung des Gabelbaumes, so daß die Gefahr besteht, daß die in Eingriff stehenden Gewinde der Innen- und Außenhülse bei der Verriegelung des gattungsgemäßen Gabelbaumes sich festfressen und infolgedessen die Verriegelung nur unter großen Kraftanstrengungen und oft nur mit Hilfe von Werkzeugen gelöst werden kann. Weiterhin ist die bekannte Verriegelungsvorrichtung verhältnismäßig aufwendig und umständlich in der Handhabung.In a length-adjustable boom of this type known from EP 0317661 A1, the outer sleeves provided with an internal thread are screwed onto the inner sleeves having a corresponding external thread in order to lock the main spars with the extension bars. The harnesses that are mainly used today on surfboards cause a strong torsional stress on the boom, so that there is a risk that the engaged threads of the inner and outer sleeves seize when locking the generic boom and consequently the locking only with great effort and often can only be solved with the help of tools. Furthermore, the known locking device is relatively complex and cumbersome to use.

Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäßen Gabelbaum im Hinblick auf eine größere Funktionssicherheit und eine einfachere Handhabung der Verriegelungsvorrichtung weiterzuentwickeln.The invention is based, to further develop the generic boom with a view to greater reliability and easier handling of the locking device the task.

Diese Aufgabe ist erfindungsgemäß gelöst durch einen längenverstellbaren Gabelbaum mit den Merkmalen des Patentanspruchs 1.This object is achieved according to the invention by a length-adjustable boom with the features of patent claim 1.
