Abstract

Mast extension with pulley block running on the inside and having rotatably mounted pulleys and a return spring. Mast extensions of known type are produced in such a way that, due to the twist of every rigging on the market, this rigging often turns in on itself during release and thus twists together due to the narrowness of the tube in which up to 6 rope lengths often run, and the pulley block consequently ceases to function. Laborious dismantling of the entire unit is then inevitable. The object of the invention is therefore to provide the user with a mast extension which makes the twisting of the pulley block impossible. In the subject-matter according to the invention, this is achieved in that the pulleys located in the tube are provided with rotatable receptacles and in addition a return spring is fastened to the latter, the rotatable receptacle having the task of absorbing the twist of the rigging, and the return spring having the task of always keeping the rigging which runs on the inside slightly tensioned.

Description

Die Erfindung betrifft eine Mastverlängerung für Segelsurfmasten.The invention relates to a mast extension for sailing surf masts.

Die heute im Handel befindlichen Segel sind fast alle mit unter­ schiedlich langen Vorlieken ausgestattet. Um nun nicht bei Ge­ brauch verschiedenen Segeln auch verschieden lange Masten haben zu müssen, bedient man sich zweckmäßiger Weise einer Mastver­ längerung.Most of the sails on the market today are under equipped with different lengths of luff. So now not with Ge need different sails to have masts of different lengths to have to use a Mastver expediently extension.

Die derzeit auf dem Markt befindlichen Segel sind so konstruiert, daß ein Trimmen des Segels an den Befestigungspunkten ohne Flaschen­ zug unmöglich ist. Befestigt man nun das Segel an der Mastfußver­ längerung und spannt das Segel mittels eines außenliegenden Flaschen­ zuges, so schafft man eine gefährliche Fußangel, welche zu erheb­ lichen Verletzungen des Benutzers führen kann.The sails currently on the market are designed to that trimming the sail at the attachment points without bottles train is impossible. Now attach the sail to the mast base lengthening and tensioning the sail using an external bottle pulling, so you create a dangerous toe, which is too high injuries to the user.

Aus diesem Grunde legt man bei hochwertigen Verlängerungen den Flaschenzug in das Grundrohr der Verlängerung.For this reason, high-quality extensions are used Pulley in the base tube of the extension.

Dies hat jedoch zur Folge, daß bei nicht ausgereiften Konstruktionen die Funktionalität der Einrichtung verloren geht oder aber sehr un­ sicher ist.However, this has the consequence that in the case of immature constructions the functionality of the device is lost or very un for sure is.

Der Erfindung liegt daher die Aufgabe zu Grunde, das Funktionieren der Einrichtung zu gewährleisten und zwar derart, daß die Auf­ nahmen 5. der Rollen 1 + 3 drehbar gelagert sind und somit die Rollen sich entsprechend dem Drall des Tauwerks immer anpassen können.The invention is therefore based on the object to ensure the functioning of the device in such a way that on the 5th of the roles 1 + 3 are rotatably mounted and thus the roles can always adapt according to the twist of the rope.

Die Rückholfeder 6. andererseits beim Lösen des Flaschenzuges das Flaschenzugseil immer auf Spannung hält und sich die im Rohr befindlichen Taue nicht miteinander Vertörnen können.The return spring 6. on the other hand, when loosening the pulley, always keeps the pulley cable under tension and the ropes in the tube cannot get lost with each other.

1. Mastverlängerung für Masten von Segelsurfbrettern, bestehend aus einem Rohr und in dem Rohr über Rollen laufendes Tau­ werk oder Rundschnurgummi.1. Mast extension for masts of sailing surfboards, consisting dew running from a tube and in the tube via rollers movement or round cord rubber. Am Rohr befindet sich eine Öffnung als Austritt des zum Segel führenden Tauwerks, eine zweite Öffnung durch welche ein Betätigungstau nach außen geführt wird, dadurch gekennzeichnet, daß die Rolle 1. an der Kappe 2. drehbar gelagert ist und die Rolle 3., welche vom Tau 4. frei schwebend gehalten wird, am unteren Ende eine Aufnahme 5. zum Befestigen von Tauwerk oder Gummi hat, welches eben­ falls drehbar gelagert ist, und daß an der drehbaren Auf­ nahme 5 eine Rückholfeder befestigt ist, welche sowohl an der Kappe 2. als auch am unteren Rohrende 7. befestigt sein kann. Ist die Rückholfeder 6. an der Kappe 2. befestigt, so wird diese über die Rolle 8. zur Kappe umgelenkt.There is an opening on the tube as the outlet of the rope leading to the sail, a second opening through which an actuating rope is led to the outside, characterized in that the roller 1. is rotatably mounted on the cap 2. and the roller 3. which is from the Tau 4th is kept floating, at the lower end a receptacle 5th for attaching rope or rubber, which is just if rotatably mounted, and that on the rotatable 5 on a return spring is attached, which both on the cap 2nd can also be attached to the lower pipe end 7 . If the return spring 6 is attached to the cap 2 , then this is deflected to the cap by the roller 8 . 2. Mastverlängerung nach Anspruch 1, dadurch gekenn­ zeichnet, daß die im Rohr laufenden Rollen 1 und 3 drehbare Aufnahme 5. haben.2. Mast extension according to claim 1, characterized in that the rollers running in the tube 1 and 3 have a rotatable receptacle 5th . 3. Mastverlängerung nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, daß an der drehbaren Aufnahme 5. eine Rückholfeder 6. befestigt ist um beim Lösen des Betätigungstauwerkes die Rolle 3. auf Spannung zu halten und somit ein Vertörnen des laufenden Tauwerks zu ver­ hindern.3. mast extension according to claims 1 and 2, characterized in that on the rotatable receptacle 5. a return spring 6. is attached to keep the role 3. when releasing the actuating rope to tension and thus to prevent verduring of the running cordage ver.
