Abstract
Description
In Segelyachten kommen vorwiegend Masten aus Aluminiumhohlprofilen zum Einsatz. In diese werden Fallen, Stromleitungen oder ähnliches eingezogen.Masts made of hollow aluminum profiles are mainly used in sailing yachts. In this will be Traps, power lines or the like pulled in.
Beim Liegen im Hafen oder vor Anker wird durch Schwell oder Sog und Wellenschlag eine schwingende Bewegung des Bootes unter anderem um die Schiffslängsachse hervorgerufen. Diese verursacht, daß die im Mast befindlichen oben genannten Bauteile von innen gegen den Mast schlagen. Das erzeugt ein monotones, schlagendes Geräusch, das unter anderem und vor allem in den Nachtstunden sehr störend ist.When lying in the harbor or at anchor, swell or suction and wave blows make a swinging one Movement of the boat caused, among other things, around the longitudinal axis of the ship. This causes the Knock the above-mentioned components in the mast against the inside of the mast. That creates a monotonous, pounding noise, which among other things and especially disturbing at night is.
Zur Bekämpfung dieser Geräusche wird ein schlauchähnliches Gebilde in den Mast eingezogen. Ein Aufblasen dieses "Schlauches" bewirkt, daß die lärmverursachenden Bauteile von innen gegen die Wand des Mastes gedrückt werden und somit ständig anliegen. Das oben beschriebene "Schlagen" wird dadurch verhindert.To combat these noises, a hose-like structure is drawn into the mast. On Inflating this "hose" causes the noise-causing components to hit the wall from the inside of the mast are pressed and are therefore always in contact. The "beating" described above is thereby prevented.
Zum Bedienen des im Mast laufenden Gutes wird zuvor das Medium, das den "Schlauch" füllt, abgelassen. Ein wiederholtes Aufblasen ist ohne Weiteres jederzeit möglich.To operate the material running in the mast, the medium that fills the "hose" is first drained. Repeated inflation is easily possible at any time.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Es zeigen:An embodiment is shown in the drawing. Show it:
Fig. 1 den Längsschnitt eines Mastes mit der darin befindlichen Erfindung, in aufgeblasenem Zustand, Fig. 1 is a longitudinal section of a mast with the invention therein, in the inflated state,
Fig. 2:
1 - Längsschnitt eines Mastbereiches, in dem sich ein aufblasbarer Teil des
"Schlauches" befindet, "Schlauch" in unaufgeblasenem Zustand,
2 - der Querschnitt zu Ansicht 1,
3 - der gleiche Längsschnitt wie 1, jedoch der "Schlauch" in aufgeblasenem Zustand,
4 - der Querschnitt zu Ansicht 3. Fig. 2:
1 - longitudinal section of a mast area in which an inflatable part of the "tube" is located, "tube" in the uninflated state,
2 - the cross section to view 1,
3 - the same longitudinal section as 1, but the "tube" in the inflated state,
4 - the cross section to view 3.
In Fig. 1 ist der in den Mast eingebaute "Schlauch" dargestellt. Der "Schlauch" besteht neben dem oberen Endstück 1 und dem unteren Endstück 2 mit Ventil 3 im wesentlichen aus zwei, untereinander dicht verbundenen Bauteilkomponenten, ein nichtaufblasbarer 4 und ein aufblasbarer Teil 5.In Fig. 1 the "hose" built into the mast is shown. In addition to the upper end piece 1 and the lower end piece 2 with valve 3, the “tube” essentially consists of two component components which are tightly connected to one another, a non-inflatable part 4 and an inflatable part 5 .
Durch eine Bohrung im Toppbeschlag 6 des Mastes 7 wird der "Schlauch" eingeführt und dort verschraubt. Im unteren Bereich erhält der Mast 7 ebenfalls eine Bohrung, durch die das Ventil 3 am unteren Endstück 2 gesteckt und verschraubt wird.The "hose" is inserted through a hole in the top fitting 6 of the mast 7 and screwed there. In the lower area, the mast 7 also has a hole through which the valve 3 is inserted and screwed on the lower end piece 2 .
Die Anordnung der aufblasbaren Bauteile 5 hängt von der Lage der Beschläge des jeweiligen Mastes ab, in dem dieser zum Einsatz kommen soll. Zu den Beschlägen zählen unter anderem der Vorstagbeschlag 8, der Spibeschlag 9, der Beschlag für die Salinge 10 sowie der Lümmelbeschlag für den Großbaum 13. Da diese Beschläge unter anderem mit spitzen, selbstschneidenden Blechtreibschrauben befestigt werden, sind in diesen Bereichen nichtaufblasbare Bauteile 4 vorgesehen, um den "Schlauch" vor Beschädigungen zu schützen.The arrangement of the inflatable components 5 depends on the position of the fittings of the respective mast in which it is to be used. The fittings include, among other things, the forestay fitting 8 , the spib fitting 9 , the fitting for the spreaders 10 and the lumber fitting for the large boom 13 . Since these fittings are fastened, among other things, with pointed, self-tapping self-tapping screws, non-inflatable components 4 are provided in these areas in order to protect the “hose” from damage.
In Fig. 2, 3 ist in Längs- und Querschnitten das Prinzip der Schalldämmung dargestellt. Die Fallen für das Vorsegel 11 und das Hauptsegel 12 sowie die Stromleitung 13 werden im aufgeblasenen Zustand des "Schlauches" 4, 5 von diesem von innen gegen den Mast 7 gedrückt. In unaufgeblasenem Zustand stört der "Schlauch" die Bewegungsfreiheit der Fallen nicht.In Fig. 2, 3 in longitudinal and cross sections of the principle of the sound is shown. The traps for the foresail 11 and the main sail 12 and the power line 13 are pressed from the inside against the mast 7 from the inside when the "hose" 4, 5 is inflated. When not inflated, the "tube" does not interfere with the freedom of movement of the traps.
