   PATENTANSPRÜCHE
1. Katamaran, dadurch gekennzeichnet, dass ein Teil oder Teile des Vorschiffes, zum Zwecke des Wiederaufrichtens des Bootskörpers, um eine Querachse über Deck des Bootes zum Achterschiff beiholbar und wieder in die Normal lage zurückholbar ist bzw. sind.



   2. Katamaran nach Patentanspruch 1, dadurch gekennzeichnet, dass Mittel vorhanden sind um das Achterschiff, zum Zwecke des Eintauchens beim Drehen des Bootskörpers, zu fluten und wieder leerzupumpen.



   Katamarane bestehen aus zwei Rümpfen, die durch Querträger parallel miteinander verbunden sind. Dieser Bootstyp kommt hauptsächlich als Segelboot vor. Mehrrumpfboote   dicser    Bauart haben sich in der Praxis bewährt; sie zeichnen sich besonders durch ihre Geschwindigkeit aus.



   Katamarane verfügen gewöhnlich über eine hohe Anfangsstabilität, so dass Kenterungen selten vorkommen. Wenn jedoch, durch das Zusammentreffen ungünstiger Umstände, ein Katamaran dennoch kentert, so ist ein Wiederaufrichten grösserer Boote ohne fremde Hilfe so gut wie unmöglich.



  Besonders auf hoher See haben solche Unfälle schon oft zu Verlusten von Menschenleben geführt.



   Der Erfindung liegt die Aufgabe zugrunde, durchgekenterte Katamarane durch bordeigene Mittel wieder aufzurichten.



   Erfindungsgemäss wird dies dadurch erreicht, dass ein Teil oder Teile des Vorschiffes um eine Querachse, über Deck des Bootes zum Achterschiff beiholbar und wieder in die Normallage zurückholbar ist. Zweckmässig ist es, wenn gleichzeitig das Achterschiff geflutet und wieder   leergepumpt    werden kann.



   Im folgenden wird anhand der beiligenden Zeichnungen ein Ausführungsbeispiel schematisch beschrieben.



   Es zeigen:
Fig. 1 Draufsicht und Seitenansicht eines Katamarans.



   Fig. 2 Den Katamaran durchgekentert.



   Fig. 3 Beginn des Aufrichtevorgangs: Die Stützen C werden senkrecht zum Deck geklappt und arretiert. Das bewegliche Vorschiffsteil wird entriegelt. Die Flutungsklappen in den Rümpfen werden geöffnet.



   Fig. 4 bis 6 Mit der Seilwinde A werden das Vorschiffsteil und das Achterschiff zusammengezogen. Vom Gewicht des Vorschiffsteils befreit, wird das Einsinken des Achterschiffs erleichtert.

 

   Fig. 7 bis 8 Hat sich der Katamaran weit genug gedreht, so wird das Wasser aus den Rümpfen gepumpt.



   Fig. 9 bis 12 Mit der Winde B wird das Vorschiffsteil in seine Ausgangslage gezogen und dort wieder verriegelt.



   Der Aufrichtemechanismus besteht, im Prinzip, aus einer Seilwinde A zum Beiholen und einer Seilwinde B zum Zurückholen des Vorschiffsteils, sowie Stützen C und mehreren Umlenkrollen.



   Das Vorschiff wirkt als Auftriebskörper. Verdrängung und Auftrieb des Katamarans sind so ausgelegt, dass das Achterschiff nicht weiter eintaucht, als für den   Aufrichte-    vorgang nötig ist.



   Wird beim Segel-Katamaran der Mast vor dem Wiederaufrichten (nach achtern) gelegt, so kann das Vorschiff in einem Teil bleiben.



   Soll der Mast beim Wiederaufrichten stehen bleiben, so muss das Vorschiff in Teilen, an Backbord und Steuerbord, am Rigg vorbei bewegt werden.

   PATENT CLAIMS
1. Catamaran, characterized in that a part or parts of the foredeck, for the purpose of straightening the hull, can be made up about a transverse axis above the deck of the boat to the aft ship and can be or are returned to the normal position.



   2. Catamaran according to claim 1, characterized in that means are available to flood the aft ship, for the purpose of immersion when turning the hull, and to pump it back empty.



   Catamarans consist of two hulls that are connected in parallel by cross beams. This type of boat mainly occurs as a sailing boat. Multi-hull boats of this type have proven themselves in practice; they are particularly characterized by their speed.



   Catamarans usually have high initial stability, so capsizing is rare. However, if a catamaran capsizes due to the coincidence of unfavorable circumstances, it is almost impossible to straighten up larger boats without outside help.



  Such accidents have often resulted in loss of life, particularly on the high seas.



   The invention has for its object to re-erect capsized catamarans by on-board means.



   This is achieved according to the invention in that a part or parts of the fore ship can be made up about a transverse axis, over the deck of the boat to the aft ship and can be brought back into the normal position. It is useful if the aft ship can be flooded and pumped empty again at the same time.



   An exemplary embodiment is described schematically below with reference to the accompanying drawings.



   Show it:
Fig. 1 top view and side view of a catamaran.



   Fig. 2 capsized the catamaran.



   Fig. 3 Beginning of the erection process: The supports C are folded perpendicular to the deck and locked. The movable fore section is unlocked. The flooding flaps in the hulls are opened.



   Fig. 4 to 6 With the cable winch A, the foreship part and the aft ship are pulled together. Freed from the weight of the fore section, the sinking of the aft ship is facilitated.

 

   Fig. 7 to 8 If the catamaran has turned far enough, the water is pumped out of the hulls.



   Fig. 9 to 12 With the winch B, the bow section is pulled into its starting position and locked there again.



   In principle, the raising mechanism consists of a winch A for pulling in and a winch B for pulling back the fore section, as well as supports C and several pulleys.



   The foredeck acts as a buoyancy aid. The catamaran's displacement and buoyancy are designed in such a way that the aft ship does not dive further than is necessary for the lifting process.



   If the mast of the sailing catamaran is laid before it is re-erected (aft), the foredeck can remain in one part.



   If the mast is to remain standing when it is being erected, the fore ship must be moved in parts, to port and starboard, past the rig.

Claims

PATENT CLAIMS 1. Catamaran, characterized in that a part or parts of the foredeck, for the purpose of straightening the hull, can be made up about a transverse axis above the deck of the boat to the aft ship and can be returned to the normal position.

2. Catamaran according to claim 1, characterized in that means are available to flood the aft ship, for the purpose of immersion when turning the hull, and to pump it back empty.

Catamarans consist of two hulls that are connected in parallel by cross beams. This type of boat mainly occurs as a sailing boat. Multi-hull boats of this type have proven themselves in practice; they are particularly characterized by their speed.

Catamarans usually have high initial stability, so capsizing is rare. However, if a catamaran capsizes due to the coincidence of unfavorable circumstances, it is almost impossible to straighten up larger boats without outside help.

Such accidents have often resulted in loss of life, particularly on the high seas.

The invention has for its object to re-erect capsized catamarans by on-board means.

This is achieved according to the invention in that a part or parts of the fore ship can be made up about a transverse axis, over the deck of the boat to the aft ship and can be brought back into the normal position. It is useful if the aft ship can be flooded and pumped empty again at the same time.

An exemplary embodiment is described schematically below with reference to the accompanying drawings.

Show it: Fig. 1 top view and side view of a catamaran.

Fig. 2 capsized the catamaran.

Fig. 3 Beginning of the erection process: The supports C are folded perpendicular to the deck and locked. The movable fore section is unlocked. The flooding flaps in the hulls are opened.

Fig. 4 to 6 With the cable winch A, the foreship part and the aft ship are pulled together. Freed from the weight of the fore section, the sinking of the aft ship is facilitated.

Fig. 7 to 8 If the catamaran has turned far enough, the water is pumped out of the hulls.

Fig. 9 to 12 With the winch B, the bow section is pulled into its starting position and locked there again.

In principle, the raising mechanism consists of a winch A for pulling in and a winch B for pulling back the fore section, as well as supports C and several pulleys.

The foredeck acts as a float. The catamaran's displacement and buoyancy are designed in such a way that the aft ship does not dive further than is necessary for the raising process.

If the mast of the sailing catamaran is laid before it is re-erected (aft), the foredeck can remain in one part.

If the mast is to remain standing during re-erection, the fore ship must be moved in parts, on port and starboard, past the rig. ** WARNING ** End of CLMS field could overlap beginning of DESC **.
