Abstract

The watercraft (1) has two oar handles (3a, 3b) that are actuated by a passenger of the watercraft. The oar handles stay in connection with a control unit, which controls a power-actuated driving motor based on the operation of the oar handles. The driving motor is connected with a ship propeller for driving the watercraft, where each handle is connected with a generator for generating current. An overcontrol device is provided for decoupling the movement of oars (4a, 4b) from the movement of the oar handles. An independent claim is also included for a method for operating a watercraft.

Description

Die Erfindung betrifft ein Verfahren zum Betreiben eines Wasserfahrzeugs und ein Wasserfahrzeug mit mindestens zwei Rudergriffen, die dazu bestimmt sind, von einem Insassen des Fahrzeugs betätigt zu werden, um dieses anzutreiben.The invention relates to a method for operating a watercraft and a watercraft having at least two rudder handles, which are intended to be actuated by an occupant of the vehicle in order to drive this.

Als "Ruder" werden in dem Zusammenhang dieser Erfindung die typischen Antriebselemente eines Ruderbootes bezeichnet, die in der nautischen Fachsprache mit dem Begriff "Riemen" identifiziert werden. Mit der Bezeichnung "Betätigung" wird hier die typische Ruderbewegung bei herkömmlichen Ruderbooten verstanden, die Vortrieb durch eine Zugbewegung am Rudergriff erzeugen, während die Ruderblätter eintauchen.As "rudders" in the context of this invention, the typical driving elements of a rowing boat are referred to, which are identified in the nautical terminology with the term "belt". The term "actuation" is understood here as the typical rudder movement in conventional rowing boats, which generate propulsion by a pulling movement on the rudder handle while the rudder blades are submerged.

Es sind einerseits muskelbetriebene Wasserfahrzeuge bekannt, die beispielsweise als Ruderboote, Tretboote oder dergleichen ausgebildet sind. Andererseits sind motorbetriebene Wasserfahrzeuge, wie etwa Elektroboote bekannt, die über Schiffschrauben, Jetantriebe oder dergleichen angetrieben sind. Die Steuerung dieser motorbetriebenen Wasserfahrzeuge erfolgt üblicherweise entweder direkt über einen Außenbordmotor oder über ein Steuerrad in Verbindung mit einem Wählhebel für die Fahrgeschwindigkeit.On the one hand, muscle-operated watercraft are known, which are designed, for example, as rowing boats, pedal boats or the like. On the other hand, motorized watercraft, such as electric boats are known, which are powered by marine propellers, Jet drives or the like. The control of these motorized watercraft is usually either directly via an outboard motor or via a steering wheel in conjunction with a selector lever for the driving speed.

Die FR 2 332 904 A zeigt ein Boot, das von einer Person in der Art eines Ruderboots über Rudergriffe angetrieben wird, wobei diese Rudergriffe jedoch nicht mit Rudern in Verbindung stehen, sondern über einen hydraulischen Mechanismus eine Schiffsschraube antreiben. Ferner zeigt die DE 203 16 652 U die alle Merkmale des Oberbegriffs des Anspruchs 1 offenbarr einen Bootsantrieb, bei dem durch eine ruderartige Bewegung Antriebsflossen betätigt werden können. Zur Verstärkung kann ein Hilfsmotor vorgesehen sein. Beide Konzepte ermöglichen durch die Beschränkung auf die menschliche Muskelkraft nur sehr bescheidene Fahrleistungen, was sich auch bei Verwendung eines Hilfsmotors nicht ändert, da dieser bei direkter Kopplung im Antriebsstrang nur eine sehr geringe Leistung aufweisen kann, wenn die Betätigung durch die Person nicht in unzulässiger Weise beeinflusst werden soll.The FR 2 332 904 A shows a boat, which is driven by a person in the manner of a rowing boat over rowing handles, but these rudder handles are not associated with rudders, but drive via a hydraulic mechanism a propeller. Furthermore, the shows DE 203 16 652 U all the features of the preamble of claim 1 evidently a boat drive in which drive fins can be operated by a rudder-like movement. For reinforcement, an auxiliary motor may be provided. Both concepts allow by the restriction to human muscle power only very modest performance, which does not change even when using an auxiliary engine, as this can have only a very low performance with direct coupling in the drive train, if the operation by the person is not inadmissible to be influenced.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zum Betreiben eines Wasserfahrzeugs anzugeben und ein Wasserfahrzeug zu schaffen, das grundsätzlich wie ein Ruderboot betätigt wird und dem Benutzer das Fahrgefühl eines Ruderbootes vermittelt, jedoch gleichzeitig wesentlich höhere Fahrgeschwindigkeiten ermöglicht und die Möglichkeit bietet, den Trainingseffekt für den Benutzer in einer vorgegebenen Weise zu steuern.Object of the present invention is to provide a method for operating a watercraft and to create a watercraft that is basically operated as a rowing boat and the user gives the feel of a rowing boat, but at the same time much higher speeds and provides the ability to control the training effect for the user in a predetermined manner.

Erfindungsgemäß werden diese Aufgaben dadurch gelöst, dass die Rudergriffe mit einer Steuerungseinheit in Verbindung stehen, die mindestens einen fremdbetätigten Antriebsmotor des Fahrzeugs in Abhängigkeit von der Betätigung der Rudergriffe steuert. Wesentlich an der vorliegenden Erfindung ist, dass die Rudergriffe primär dazu dienen, einer Steuerungseinheit Signale für die gewünschte Fahrgeschwindigkeit und Fahrrichtung zu geben.According to the invention, these objects are achieved in that the rudder handles are connected to a control unit which controls at least one externally actuated drive motor of the vehicle in response to the operation of the rudder handles. The essential feature of the present invention is that the rudder handles serve primarily to give signals to the control unit for the desired driving speed and driving direction.

Eine bevorzugte Ausführungsvariante der Erfindung sieht vor, dass jeder Rudergriff gesondert einen Antriebsmotor ansteuert. Die Antriebsmotoren sind dabei bevorzugt seitlich zueinander versetzt, so dass eine unterschiedliche Betätigung der Rudergriffe auch eine unterschiedliche Fahrtrichtung bewirkt. Um die Wendigkeit zu erhöhen, kann zusätzlich ein Steuerruder vorgesehen sein, das in Abhängigkeit von der Betätigung der Rudergriffe angesteuert wird.A preferred embodiment of the invention provides that each rudder handle separately drives a drive motor. The drive motors are preferably laterally offset from one another, so that a different actuation of the rowing handles also causes a different direction of travel. In order to increase the maneuverability, a rudder may additionally be provided, which is controlled in dependence on the operation of the rudder handles.

Der Antrieb des Wasserfahrzeugs selbst kann einerseits durch Ruder erfolgen, es kann jedoch auch eine Schiffsschraube oder ein Jetantrieb vorgesehen sein. Bei einem Antrieb des Wasserfahrzeugs über Ruder können diese sowohl fest mit den Rudergriffen gekoppelt sein, als auch teilweise oder vollständig von den Rudergriffen entkoppelt sein, wobei im letzteren Fall der Antrieb ausschließlich über den Antriebsmotor erfolgt.The propulsion of the watercraft itself can be done on the one hand by rudders, but it can also be provided a propeller or a jet propulsion. In a drive of the vessel over rudder these can be both firmly coupled to the rudder handles, as well as partially or completely decoupled from the rudder handles, in the latter case, the drive is exclusively via the drive motor.

Um die vom Benutzer aufzubringende Leistung in Relation zur Fahrtgeschwindigkeit genau einstellen zu können, kann jeder Rudergriff mit einem Generator oder mit einer Bremseinrichtung verbunden sein.In order to be able to precisely adjust the power to be applied by the user in relation to the travel speed, each rudder handle can be connected to a generator or to a braking device.

In der Folge wird die vorliegende Erfindung anhand der in den Figuren dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:

Fig. 1
eine erste Ausführungsvariante der Erfindung;
Fig. 2
eine zweite Ausführungsvariante der Erfindung; und
Fig. 3
eine weitere Ausführungsvariante jeweils in einer schematischen Darstellung.
As a result, the present invention will be explained in more detail with reference to the embodiments illustrated in FIGS. Show it:
Fig. 1
a first embodiment of the invention;
Fig. 2
a second embodiment of the invention; and
Fig. 3
a further embodiment in each case in a schematic representation.

Fig. 1 zeigt ein allgemein mit 1 bezeichnetes Wasserfahrzeug in der Form eines Ruderbootes mit einem Sitz 2 für einen Benutzer. Es ist offensichtlich, dass neben diesem einen Sitz 2 weitere nicht dargestellte Sitze vorgesehen sein können, die Platz für weitere Benutzer bieten, um das Boot beispielsweise in der Form eines Ruderachters auszubilden. Fig. 1 shows a generally designated 1 vessel in the form of a rowing boat with a seat 2 for a user. It is obvious that in addition to this one seat 2 further seats, not shown, may be provided, provide space for additional users to form the boat in the form of, for example, a rowman.

Seitlich neben dem Sitz 2 sind Rudergriffe 3a, 3b vorgesehen, die in dieser Ausführungsvariante starr mit Rudern 4a, 4b in Verbindung stehen, die an Punkten 5a, 5b gelenkig mit dem Ruderboot 1 verbunden sind. Die Ruder 4a, 4b werden einerseits über die Rudergriffe 3a, 3b angetrieben und andererseits über Hydraulikzylinder 6a, 6b, die die Antriebsmotoren darstellen und von einer Hydraulikeinheit 7 angetrieben werden. Eine Steuerungseinrichtung 8 steuert die Hydraulikeinheit 7 und damit die Hydraulikzylinder 6a, 6b.On the side next to the seat 2, rowing handles 3a, 3b are provided, which in this embodiment are rigidly connected to rudders 4a, 4b, which are pivotally connected to the rowboat 1 at points 5a, 5b. The rudders 4a, 4b are driven on the one hand via the rudder handles 3a, 3b and on the other hand via hydraulic cylinders 6a, 6b, which constitute the drive motors and are driven by a hydraulic unit 7. A control device 8 controls the hydraulic unit 7 and thus the hydraulic cylinders 6a, 6b.

Mit den Rudergriffen 3a, 3b sind Sensoren 9a, 9b verbunden, die die Stellung der Rudergriffe 3a, 3b erfassen und über Steuerleitungen 10a, 10b an die Steuerungseinheit 8 übermitteln. In den Gelenkpunkten 5a und 5b sind zwei weitere Sensoren 11a und 11b angebracht, die den Gelenkdruck, erzeugt durch das Rudern des Ruderers, messen und über Steuerleitungen 12a und 12b an die Steuereinheit 8 übermitteln.Sensors 9a, 9b are connected to the rudder handles 3a, 3b, which detect the position of the rudder handles 3a, 3b and transmit them to the control unit 8 via control lines 10a, 10b. In the hinge points 5a and 5b, two further sensors 11a and 11b are mounted, which measure the joint pressure generated by the rowing of the rower, and transmit via control lines 12a and 12b to the control unit 8.

Die Ausführungsvariante der Fig. 1 stellt ein Ruderboot mit Servoantrieb dar, das heißt, dass die Betätigung der Ruder 4a, 4b zwar grundsätzlich über die Rudergriffe 3a, 3b erfolgt, jedoch über den Antriebsmotor 7; 6a, 6b unterstützt wird, so dass eine wesentlich höhere Fahrgeschwindigkeit erreichbar ist. Dabei ist die Unterstützung proportional zu der aufgebrachten Kraft anzusehen, wobei der Druck in den Sensoren 11a und 11b als Steuergröße herangezogen wird. Je mehr Kraft der Ruderer selber aufbringt, desto stärker wird er von dem Antriebsmotor 7; 6a, 6b unterstützt.The variant of the Fig. 1 represents a rowing boat with servo drive, that is, that the operation of the rudder 4a, 4b, although basically via the rudder handles 3a, 3b, but via the drive motor 7; 6a, 6b is supported, so that a much higher driving speed can be achieved. The support is proportional to the force applied, the pressure in the sensors 11a and 11b being used as the control variable. The more force the rower himself applies, the stronger he gets from the drive motor 7; 6a, 6b supported.

Bei der Ausführungsvariante von Fig. 2 sind im Unterschied zu der von Fig. 1 keine Ruder vorgesehen, das heißt, dass die Rudergriffe 3a, 3b ausschließlich der Steuerung des Ruderbootes 1 dienen. Die Ruderbewegung des Ruderers wird dabei bevorzugt zu zwei Generatoren 17a und 17b geleitet, die mit den Handgriffen 3a, 3b über Riemenantriebe 24a, 24b in Verbindung stehen, um der Betätigung der Rudergriffe 3a, 3b einen entsprechenden Widerstand entgegenzusetzen. Drehzahlsensoren 18a und 18b sind in den Motor oder Riementrieb eingebaut, um die Drehzahl an die Steuerungseinrichtung 8 zu übermitteln. Diese steuert die Antriebsmotoren 16a, 16b proportional zur Drehzahl des an der gleichen Seite angebrachten Generators.In the embodiment of Fig. 2 are different from that of Fig. 1 no rudders provided, that is, the rudder handles 3a, 3b serve exclusively the control of the rowing boat 1. The rudder movement of the rower is preferably directed to two generators 17a and 17b, which are connected to the handles 3a, 3b via belt drives 24a, 24b in order to oppose the operation of the rudder handles 3a, 3b, a corresponding resistance. Speed sensors 18a and 18b are incorporated in the engine or belt drive to communicate the speed to the controller 8. This controls the drive motors 16a, 16b in proportion to the speed of the generator mounted on the same side.

Zur Vergleichmäßigung der Antriebsleistung kann auch eine Schwungscheibe mit den Generatoren verbunden sein, oder es kann eine elektronische Schaltung die Vergleichmäßigung bewirken. Es sind dabei Software sowie Hardware Lösungen einsetzbar.To even out the drive power and a flywheel may be connected to the generators, or it may be an electronic circuit Equalization effect. Software and hardware solutions can be used.

Alternativ dazu kann auch wie bei der ersten Ausführungsvariante die Stellung der Rudergriffe 3a, 3b durch Sensoren 9a, 9b erfasst und an eine Steuerungseinrichtung 8 übermittelt werden. Diese steuert die Antriebsmotoren 16a, 16b entsprechend der Betätigung der Rudergriffe 3a, 3b an, die ihrerseits Schiffsschrauben 15a, 15b antreiben.Alternatively, as in the first embodiment, the position of the rudder handles 3a, 3b detected by sensors 9a, 9b and transmitted to a control device 8. This controls the drive motors 16a, 16b in accordance with the operation of the rudder handles 3a, 3b, which in turn drive propellers 15a, 15b.

Die Antriebsmotoren 16a, 16b können sowohl als Elektromotoren als auch als Brennkraftmaschinen mit innerer Verbrennung ausgebildet sein. Zusätzlich kann ein Steuerruder 14 vorgesehen sein, das von einem Servomotor 13 angetrieben wird, der ebenfalls von der Steuerungseinrichtung 8 angesteuert wird.The drive motors 16a, 16b can be designed both as electric motors and as internal combustion engines. In addition, a rudder 14 may be provided, which is driven by a servomotor 13, which is also controlled by the control device 8.

Die Ausführungsvariante von Fig. 3 weist Ruder 4a, 4b auf, die jedoch im Unterschied zur Ausführungsvariante von Fig. 1 von den Rudergriffen 3a, 3b entkoppelt sind. Die Ruder 4a, 4b werden von Antriebsmotoren 26a, 26b über Antriebsriemen 27a, 27b angetrieben oder über eine (nicht dargestellte) Hydraulikeinrichtung und über Hubmotoren 28a und 28b beim Ruderholen in die Höhe gehoben. Die Antriebsmotoren 26a, 26b werden wie bei den vorigen Ausführungsvarianten von einer Steuerungseinrichtung 8 angesteuert und taktgleich zur Ruderbewegung des Ruderers betrieben.The variant of Fig. 3 has rudders 4a, 4b, which, however, unlike the variant of Fig. 1 are decoupled from the rudder handles 3a, 3b. The rudders 4a, 4b are driven by drive motors 26a, 26b via drive belts 27a, 27b or raised by means of a hydraulic device (not shown) and by lifting motors 28a and 28b during rowing. The drive motors 26a, 26b are controlled by a control device 8 as in the previous embodiment variants and operated in synchronism with the rudder movement of the rower.

Die Handgriffe 3a, 3b stehen über Riemenantriebe 24a, 24b mit Generatoren 25a, 25b in Verbindung, um der Betätigung der Rudergriffe 3a, 3b einen entsprechenden Widerstand entgegenzusetzen. Dieser Widerstand kann von der Steuerungseinrichtung 8 entsprechend dem Fahrzustand aber auch entsprechend externer Vorgaben eingestellt werden. Auf diese Weise ist es möglich, ein Trainingsprogramm vorzugeben, das dem Benutzer des Wasserfahrzeugs einen vorbestimmbaren Trainingseffekt bietet. Der Widerstand kann aber auch beispielsweise von der Herzfrequenz des Benutzers abhängig gemacht werden, sofern diese gemessen wird.The handles 3a, 3b are connected via belt drives 24a, 24b with generators 25a, 25b in order to oppose the operation of the rudder handles 3a, 3b, a corresponding resistance. This resistance can be adjusted by the control device 8 according to the driving condition but also according to external requirements. In this way it is possible to specify a training program that offers the user of the vessel a predeterminable training effect. However, the resistance can also be made dependent on the heart rate of the user, for example, if this is measured.

Der Vorteil der Ausführungsvariante von Fig. 3 besteht darin, dass das äußere Erscheinungsbild des Wasserfahrzeugs weiterhin dem eines Ruderbootes entspricht, wobei jedoch ungewöhnlich hohe Fahrgeschwindigkeiten und/oder Schlagzahlen erreichbar sind.The advantage of the variant of Fig. 3 is that the outer appearance of the vessel continues to correspond to that of a rowing boat, but unusually high speeds and / or numbers of strokes can be achieved.

Die vorliegende Erfindung ermöglicht es, ein Wasserfahrzeug zu schaffen, das eine bisher ungeahnte Funktionalität aufweist.The present invention makes it possible to provide a watercraft having a previously unimagined functionality.
