Description
Antriebsaggregat für Schlauchboote.Drive unit for inflatable boats.
Die Erfindung betrifft,ein der Fortbewegung im Wasser dienendes Antriebsaggregat,das mit einem zusammenlegbaren Schlauchbootskörper fest verbunden ist und zwar so,daß einmal keinerlei Teile des Antriebs,wie Schiffsschraube, Ruder u. dgl. das handliche Zusammenfalten stören und zum Anderen ein rasches Füllen der Tragschläuche ermöglicht ist0 Bekannt sind Schlauchboote mit Außenbordmotore.Das Aufblasen der Trägerschläuche mit Hand-oder Fußpumpe erfordert Kraft und Zeit. Zur Erleichterung werden deshalb u.a. Behälter mit komprimiertem Gas benützt,die das Füllen des Schlauchbootes bewerkstelligen. Der Nachteil dieses Verfahrens liegt darin, daß diese Behälter in ihrem Volumen begrenzt sind und daher nur das einmalige Füllen zulassen und nicht überall Füllstationen für die Behälter ansutre£-fen sind. Schlauch-Beiboote aber werden je- nach Verwendungszweck mehrmals in kurzen Abständen hintereinander, zusammengelegt und einsatzbereit benötigt.Der Motor muß nach dem Aufblasen der Trägerschläuche am Heck befestigt werden,wobei dann dessen Anbringung umständlich und insbesondere bei Seegang schwierig ist.The invention relates to a propulsion unit which is used for locomotion in the water is firmly connected to a collapsible dinghy body in such a way that once no parts of the drive, such as propeller, rudder and the like. The handy one Interfere with folding and, on the other hand, enables the support tubes to be filled quickly Is0 known are inflatables with outboard motors. The inflation of the carrier hoses using a hand or foot pump requires strength and time. Therefore, to make things easier Among other things, containers with compressed gas are used to fill the inflatable boat. The disadvantage of this method is that these containers in their volume are limited and therefore only allow one-time filling and not filling stations everywhere for the containers are suitable. Inflatable dinghies, however, are used depending on the intended use needed several times at short intervals in a row, folded and ready for use The engine must be attached to the stern after the carrier hoses have been inflated, whereby then its attachment is cumbersome and particularly difficult in rough seas.
Diese Schwierigkeiten werden damit gelöst,daß an einem Schlauchboot üblicher Ausführung,ein mit diesem festverbundenes,wasserdichtes Gehäuse in Kastenform am Heck des Bootes angebaut wird,welches einen Antriebsmotor enthält,der sowohl das Füllen der Trägerschläuche ermöglicht als auch der Fortbewegung des Bootes dient. Der zur Fortbewegung des Bootes erforderliche Schub wird durch ein im Boden des Gehäuses eingelaßenes Schaufelrad mit den in bekannter Weise angeordneten Ansaug - und Ausstoßöffnungen erzeugt.Alle vorstehenden Teile wie Schiffsschraube, Ruder u.dgl. entfallen sodaß damit beim Zusammenlegen nur wenig Raum beansprucht wird. Das Füllen der Trägerschläuche erfolgt entweder durch einem vom Motor angetriebenen Kompressor oder Gebläse.Auch die Abgase des Motors direkt könnten verwendet werden, welche dann zweckmäßig über Filter und entsprechende Antriebsaggregat für Schlauchboote Ventile zu den Tragschläuchen geleitet werden.Dami~t in das Antriebsaggregat, wenn es außer Betrieb ist kein Wasser eindringen kann,werden alle Öffnungen z.B. für Kühl-und Ansauglust für den Antriebsmotor so angebracht, daß diese zentral wasserdicht verschloßen werden können.These difficulties are solved so that on an inflatable boat usual design, a tightly connected, waterproof box-shaped housing is attached to the stern of the boat, which contains a drive motor that has both the filling of the carrier tubes allows as well as the movement of the boat. The thrust required to move the boat is provided by an in the bottom of the Housing embedded paddle wheel with the suction arranged in a known manner - and discharge openings generated. All protruding parts such as propeller, rudder and the like are omitted so that only little space is required when they are folded. The carrier tubes are filled either by a motor-driven one Compressor or blower. Also the exhaust gases from the engine directly could be used which then appropriately through filters and appropriate Drive unit for inflatable boats, valves are routed to the support tubes. Dami ~ t in the drive unit, when it is out of operation no water can penetrate, all openings are e.g. for cooling and suction for the drive motor attached so that it is centrally watertight can be locked.
Gleichzeitig werden dabei Zündung und Brennstoffzufuhr unterbrochen.Ignition and fuel supply are interrupted at the same time.
Soll das Schlauchboot im Notfall auch als Rettungsboot eingesetzt werden können, ist es zweckmäßig noch zu dem oben beschriebenen Füllsystem einen an dieses angeschlossenen Behälter mit komprimiertem Gas vorzusehen, welcher dann im Gefahrenfall eine einmalige Füllung der Tragschläuche in kürzester Zeit ermöglicht.Should the inflatable boat also be used as a lifeboat in an emergency it is advisable to add one to the filling system described above to provide this connected container with compressed gas, which then In the event of danger, the support tubes can be filled once in a very short time.
Antriebsaggregat für Schlauchboote Ein Ausführungsbeispiel zeigt in Fig.l ein Schlauchboot in bekannter Konstruktion im Längsschnitt. Fig 2 in der Draufsicht.Drive unit for inflatable boats An exemplary embodiment is shown in Fig.l a dinghy of known construction in longitudinal section. Fig. 2 in plan view.
Fest verbunden quer am Heck des Schlauchbootes (1) wird ein aus Kunststoff oder ähnlichem Material bestehender wasserdichter Kasten (2) angeordnet,in welchem ein Antriebsmotor z.B. ein mit seiner Antriebsachse vertikal liegender Benzinmotor (3),eingebaut ist.Dieser treibt ein Schaufelrad (4) an,das von dem Leitgehäuse (5) umschloßen wird.Am Eintrittskanal (6) wird durch das Schaufelrad (4) im Betrieb Wasser-angesaugt und bei der Austrittsöffnung (7) stark beschleunigt ausgestoßen, wodurch wie bekannt durch den Rückstoß die Vorwärtsbewegung des Bootes erfolgt.A plastic unit is firmly connected across the stern of the inflatable boat (1) or similar material existing waterproof box (2) arranged in which a drive motor, e.g. a petrol engine with its drive axis vertical (3), which drives a paddle wheel (4), which is driven by the guide housing (5) At the inlet channel (6) is operated by the paddle wheel (4) Water-sucked in and expelled at the outlet opening (7) at a high speed, which, as is known, causes the boat to move forward due to the recoil.
Lenkbar ist das Boot durch den Hebel (8) der mit der Düse (9) mechanisch verbunden ist und diese in der Horizontalen bewegen kann und dadurch den austretenden Strahl aus der Mittellinie ablenkt.The boat can be steered mechanically using the lever (8) with the nozzle (9) is connected and this can move horizontally and thereby the exiting Deflects the beam from the center line.
In dem beschriebenen Kasten (2) sind auch die erforderlichen Zubehörteile wie TPnk,Zündspule,Auspufftopf uew.The required accessories are also in the box (2) described like TPnk, ignition coil, muffler etc.
untergebracht. Die zum Betrieb erforderlichen Öffnungen für Ansaug-und Kühlluft ect. sind unter einem wasserdicht verschließbarem Deckel (10) angeordnet,der beim Schließen gleichzeitig einen ZUndunterbrecher betätigt und das Brenn stoffventil absperrt. Mit dem Antriebsmotor (3) ist auch ein Luftkompressor oder Gebläse (11) gekuppelt,welcher die Tragschläuche mit Luft füllt und mit diesen direkt in Verbindung steht.housed. The openings for suction and intake required for operation Cooling air ect. are arranged under a waterproof, closable cover (10), the When closing, an ignition switch is actuated and the fuel valve is actuated at the same time shut off. The drive motor (3) is also an air compressor or blower (11) coupled, which fills the support tubes with air and connects directly to them stands.
Eine andere mögliche Anordnung ist auch über einen Filter die Abgase des Motors zur Füllung der Tragschläuche zu verwenden,was eine Vereinfachung der Anlage ergeben würde.Another possible arrangement is the exhaust gases via a filter of the motor to fill the support hoses, which simplifies the Plant would result.
Wenn die Luft in bekannter Weise aus den Tragschläuchen abgelassen wird,kann. das Schlauchboot mit dem Motorkasten zusammen in ein verhältnismäßig kleines Paket zusammengewickelt und so leicht verstaut werden.When the air is deflated from the carrier tubes in a known manner will, can. the dinghy with the engine box together in one relatively small package can be wrapped up and stowed away easily.
