Abstract
The trimaran craft is designed so that in the danger of capsizing, it can be righted again without external assistance. Each of the two floats (E) is attached by an arm (F) to a pivot point on the central hull (D) so that they may be swung upwards through an angle of at least 90 deg. To assist this operation, a frame (C) at front and rear, normally flat on the deck, can be swung up, then the outriggers are pulled up towards it by means of cables and pulleys. When the craft is upside down, these floats are erected is described, so that the hull is raised above the water level. Then the craft can be righted. For heavier craft, one float can be flooded to assist this operation, to act as a counterweight, then afterwards pumped out.
Description
Die Erfindung betrifft ein Mehrrumplboot vom Typ Trimaran.
Trimarane bestehen aus einem Hauptrumpf und zwei an Auslegern befestigten Seitenschwimmern. Dieser Bootstyp kommt fast nur als Segelboot vor. Mehrrumpfboote dieser Bauart haben sich in der Praxis bewährt. Sie zeichnen sich besonders durch ihre Geschwindigkeit aus. Durch die Seitenschwimmer, die eine stützende Funktion ausüben, ist Ballast überflüssig.
Diese Seitenschwimmer verleihen dem Boot eine grosse Stabilität, so dass Kenterungen selten vorkommen. Wenn jedoch durch das Zusammentreffen ungünstiger Umstände ein Trimaran dennoch kentert, so ist ein Wiederaufrichten des Bootes ohne fremde Hilfe so gut wie unillöglich. Besonders auf hoher See haben solche Unfälle schon zu Verlusten voil Menschenleben geführt.
Der Erfindung liegt die Aufgabe zugrunde, durchgekenterte Trimarane durch bordeigene Mittel wieder aufzurichten.
Erfindungsgemäss wird dies dadurch erreicht, dass die Seitenschwimmer, mit ihren Auslegern am Hauptrumpf in dessen Längsachse schwenkbar befestigt, über Deck desselben bis ca. 90" beiholbar und wieder in ihre normale Auslegerstellung zurückbringbar sind.
Im folgenden werden anhand der beiliegenden Zeichnungen zwei Ausführungsbeispiele der Erfindung schematisch beschrieben. Der Aufrichtemechanismus besteht in beiden Beispielen, im Prinzip, aus einer Seilwinde A zum Beiholen und einer Seilwinde B zum Zurückholen der Seitenschwimmer sowie zwei Hebestützen C und mehreren Umlenkrollen.
A usführungsbeispiel 1
Es ist hauptsächlich für kleinere Trimarane geeignet.
Es zeigen
Fig. 1 Draufsicht und Rückansicht eines Trimarans mit Hauptrumpf D, Seitenschwimmern E und Auslegern F.
Fig. 2 den Trimaran durchgekentert.
Fig. 3 Beginn des Aufrichtevorgangs: Die Hebestützen C werden senkrecht zum Deck geklappt und arretiert. Die Ausleger werden entriegelt.
Fig. 66 mit der Seilwinde A werden die Seitenschwimmer über die Hebestützen C beigeholt. Das Boot nähert sich einem labilen Gleichgewichtszustand. Je stärker das Wasser bewegt ist, desto eher wird sich der Trimaran auf eine Seite legen, Fig. 7.
Fig. 8-10 mit der Seilwinde B werden jetzt die Seitenschwimmer wieder in ihre normale Lage gezogen und dort arretiert.
A usführungsbeispiel 2
Es ist hauptsächlich für grössere Trimarane geeignet. Ein Seitenschwimmer kann geflutet und wieder leergepumpt werden. Geflutet sollen sein Auftrieb und seine Verdrängung etwa gleich sein.
Es zeigen

Fig. 12 Beginn des Aufrichtevorganges: Die Hebestützen werden senkrecht zum Deck geklappt und arretiert. Die Ausleger werden entriegelt. Die Flutungsklappen des Seitenschwimmer werden geöffnet.
Fig. 13-15 mit der Seilwinde A werden die Seitenschwimmer über die Hebestützen beigeholt. Der geflutete Seitenschwimmer wandert dabei unter dem Hauptrumpf hindurch.
Fig. 16-17 sind die Seitenschwimmer weit genug beigeholt, so wird der geflutete Seitenschwimmer leergepumpt.
Fig. 18-20 mit der Seilwinde B werden jetzt die Seitenschwimmer wieder in ihre normale Lage gezogen und dort arretiert.
PATENTANSPRUCH
Trimaran, dadurch gekennzeichnet, dass die Seitenschwimmer, mit ihren Auslegern am Hauptrumpf in dessen Längsachse schwenkbar befestigt, über Deck desselben bis ca.
90" beiholbar und wieder in ihre normale Auslegerstellung zurückholbar sind.
UNTERANSPRUCH
Trimaran nach Patentanspruch, dadurch gekennzeichnet, dass Mittel vorhanden sind um einen der Seitenschwimmer, zum Zwecke des leichteren Beiholens über Deck des Hauptrumpfes, ganz oder teilweise zu fluten und wieder leerzupumpen.
**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
The invention relates to a multi-hull boat of the trimaran type.
Trimarans consist of a main hull and two side floats attached to outriggers. This type of boat occurs almost exclusively as a sailing boat. Multihull boats of this type have proven themselves in practice. They are particularly characterized by their speed. Ballast is superfluous due to the side floats, which have a supporting function.
These side floats give the boat great stability, so that capsizing rarely occurs. If, however, a trimaran overturns due to the coincidence of unfavorable circumstances, it is almost impossible to straighten the boat again without outside help. Such accidents have already resulted in loss of life, especially on the high seas.
The invention is based on the object of erecting capsized trimarans again using on-board means.
According to the invention, this is achieved in that the side floats, with their booms attached to the main hull so as to be pivotable in its longitudinal axis, can be brought up to about 90 "over the deck and brought back into their normal boom position.
In the following, two exemplary embodiments of the invention are described schematically with reference to the accompanying drawings. The righting mechanism in both examples consists, in principle, of a cable winch A for retrieving and a cable winch B for retrieving the side floats as well as two lifting supports C and several pulleys.
Embodiment 1
It is mainly suitable for smaller trimarans.
Show it
Fig. 1 top and rear view of a trimaran with main hull D, side floats E and booms F.
Fig. 2 capsized the trimaran.
Fig. 3 Beginning of the erection process: The lifting supports C are folded and locked perpendicular to the deck. The booms are unlocked.
Fig. 66 With the cable winch A, the side floats are brought in via the lifting supports C. The boat is approaching an unstable state of equilibrium. The more the water is agitated, the sooner the trimaran will lie on one side, Fig. 7.
Fig. 8-10 with the cable winch B the side swimmers are now pulled back into their normal position and locked there.
Embodiment 2
It is mainly suitable for larger trimarans. A side float can be flooded and pumped out again. When flooded, its buoyancy and displacement should be roughly the same.
Show it
11 the trimaran capsized.
Fig. 12 Beginning of the righting process: The lifting supports are folded and locked perpendicular to the deck. The booms are unlocked. The flooding flaps of the side float are opened.
Fig. 13-15 with the cable winch A, the side floats are brought in via the lifting supports. The flooded side swimmer wanders under the main hull.
Fig. 16-17 if the side float has been brought in far enough, the flooded side float is pumped out.
Fig. 18-20 with the cable winch B the side swimmers are now pulled back into their normal position and locked there.
PATENT CLAIM
Trimaran, characterized in that the side floats, with their booms attached to the main hull so that it can pivot in its longitudinal axis, over the deck of the same up to approx.
90 "can be retrieved and returned to their normal boom position.
SUBClaim
Trimaran according to patent claim, characterized in that means are provided to completely or partially flood one of the side swimmers for the purpose of easier hauling over the deck of the main hull and to pump it empty again.
