Abstract

The centreboard (1) for the windsurfer is mounted inside a casing (2) fitted into a slot through the board. The centreboard is pivoted about a horizontal axis (6) in the casing with a flexible lead loop (3) extending through the top of the casing for simple adjustment. The centreboard is held in its setting by a spring (4) so that when striking underwater obstructions it is swung back without damage. The mounting can be applied to any windsurfer with a minimum of modification.

Description

Patentbeschreibung Technische Bezeichnung: Windsurfdrehschwert, bzw. Segelsurfdrehschwert Anwendung: Das Drehschwert mit eigenem Schwertkasten ist einsetzbar in dem vorhandenen Schwertschlitz bei Windsurfboards. Erzielbare Vorteile: - Durch selbstätiges Nachgeben bei Berührung von Grund und anderen Hindernissen wird eine unangenehme Beschädigung des Boards im Schwertschlitzbereich vermieden.Patent description Technical designation: windsurfing rotary sword, resp. Sailing Swivel Sword Application: The swivel sword with its own sword case can be used in the existing sword slot on windsurf boards. Achievable benefits: - By self-acting yielding when touching ground and other obstacles becomes one unpleasant damage to the board in the sword slot area avoided.

Selbst bei extremer Grundberührung wird der St) Uber die gesamte hintere Schwertkante auf die Boardunterseite verteilt. Even in the case of extreme grounding, the St) over the entire rear edge of the sword distributed on the underside of the board.

- Dynamische Höhenverstellung durch Vor-, bzw.- Dynamic height adjustment through forward or

Zürückklappen möglich, ohne dabei, wie die bisher Ublichen Schwerter, oberhalb der Boardoberfläche herauszuragen. Es besteht also kein Hindernis für Fuß- und Segelstellung mehr. Auberdem wird die Verletzungsgefahr bei einem möglichen Sturz vermindert. Can be folded back without, like the swords customary up to now, protrude above the board surface. So there is no obstacle for walking and feathering more. In addition, the risk of injury in a possible Fall decreased.

Universell verwendbar, vom Normalschwert bis zum Sturmschwert. Es läbt sich den Windverhältnissen auch während des Surfens durch manuelles Veretellen anpassen.Universally usable, from the normal sword to the storm sword. It The wind conditions can also be adjusted by manual adjustment while surfing adjust.

- Der durch das Zurückklappen des Schwertes nnch hinten verlagerte Lateral punkt erleichtert, vor allem bei Starkwind, den Start und die Fortbewegung durch geringere Luvgierigkeit des Boards bei gleichbleibender Maststellung.- The one shifted backwards by folding the sword back Lateral point facilitates the start and movement, especially in strong winds because the board is less windward when the mast position remains the same.

- Durch die Verringerung des Krängungsmomentes wird die Gefahr des Kentersturzes gemindert.- By reducing the heeling moment, the risk of Capsize.

- Zu den erz hinten Vorteilen bleiben die Funktionen der bisher Ublichen Steckschwerter vojl erhalten, d.h. es besteht weiterhin die Möglichkeit, das Schwert aus dem Board teilweise oder ganz herauszuziehen.- In addition to the ore rear advantages, the functions of the previously usual ones remain Steckschwerter vojl received, i.e. it is still possible to use the sword to partially or completely pull it out of the board.

Stand der Technik u.State of the art and

Kritik: - Reibungsfläch&nhielten bisher bisher die Klappschwerter in der gewünschten Stellung.Criticism: - So far, the folding swords have held the friction surface in the desired position.

Durch die Materialabnutzung kann dies keine Dauerlösung sein. Due to the wear and tear of the material, this cannot be a permanent solution.

- Die bisherigen Schwerter sind entweder von oben nicht während der Fahrt aus dem Board herausnehmbar, oder herausragende Teile behindern die Fußstellung und bilden eine Gefahrenquelle für Verletzungen.- The previous swords are either not from above during the Ride can be removed from the board, or protruding parts impede the position of the foot and are a source of danger for injuries.

- Bei den meisten Schwertarten führt starke Grundberührung zur Boardbeschädigung.- With most types of sword, heavy ground contact leads to board damage.

- Bisher ist keine dynamische Einstellung und Feststellung möglich.- So far, no dynamic setting and determination is possible.

Aufgabe: - Konstruktion eines Schwertes mit dem Ziel, auch schon für vorhandene Surfboards, die bisher mit Steckschwertern ausgerustet sind, mit dieser Konstruktion eine Umrüstungsalternative zu bieten.Task: - Construction of a sword with the aim of even for existing surfboards, which were previously equipped with plug-in swords, with this one Construction to offer a retrofit alternative.

Lösung: - Eigener Schwertkasten des Drehschwertes bietet Raum für: a) eigene Schwertdrehachse b) für federnde Schwertdrehung um den festen Drehpunkt c) für Einstellvorrichtung - Der Kreiskopfansatz des Schwertes verhindert bei jeder Schwertposition eine starke Wassereinströmung in den Schwertkasten.Solution: - The rotating sword's own sword case offers space for: a) own sword axis of rotation b) for resilient rotation of the sword around the fixed pivot point c) for adjustment device - the circular head approach of the sword prevents each Sword position a strong inflow of water into the sword case.

Weitere Ausgestaltung: (Unteranspruch) - Die Weiterentwicklung der verschiedenen Einstellungsarten des Drehschwertes innerhalb, bzw. durch Bedienteile außerhalb des schwerteigenen Schwertkastens behalten wir uns vor.Further design: (subclaim) - The further development of the different types of setting of the rotary sword within or through control units We reserve the right outside of the sword's own sword case.

- Das Prinzip des schwerteigenen Schwertkastens ermöglicht bei entsprechender Board - Konstruktion eine Versenkung des Schwertes auch in den Boardrumpf.- The principle of the sword's own sword case enables with the appropriate Board construction a sinking of the sword also in the board body.

Zweck: - Schwert ist generell erforderlich, um auf allen Kursen segeln und damit auch surfen zu k<innen.Purpose: - Sword is generally required to sail on all courses and with it also surfing to k <inside.

- Weiter ist es von Vorteil, wenn sich das Schwert bei verschiedenen Wassertiefen verstellen läßt, damit auch im flacheren Wasser noch gesurft werden kann oder durch eine GrundberUhrlmg ein Schaden am Board verhindert wird. - It is also an advantage if the sword is in different positions Water depths can be adjusted so that you can still surf in shallower water can be prevented or damage to the board is prevented by a basic rubble.

- Die Verlagerung des Lateralpunktes durch das Zurückklappen des Schwertes vermindert die Luvgierigkeit und erleichtert damit das Starten bei stärkerem Wind. - The displacement of the lateral point by folding back the Sword reduces the greediness to wind and thus facilitates starting with stronger Wind.

- Verkleinertes Krängungsmoment durch verkürzbare Scbwerttauchtiefe vermindert die Gefahr des Kentersturzes. - Reduced heeling moment due to the shortened diving depth reduces the risk of capsizing.
