Description

Die Erfindung betrifft eine steuerbare Surfbrettanordnung.The invention relates to a controllable surfboard arrangement.

Surfbretter sind hinlänglich bekannt. Bei Surfbrettern handelt es sich im englischen Sprachgebrauch um Bretter ohne Segel, auf denen ein Surfer durch den Vorschub einer Welle reiten kann. Im deutschen Sprachgebrauch spricht man hier von Wellenreiten.Surfboards are well known. Surfboards are in the English language boards without sails, on which a surfer can ride by the advance of a wave. In German parlance one speaks here of surfing.

Surfbretter haben den Nachteil, dass ohne den Vorschub der Welle eine Ausübung des Wassersports nicht möglich ist. Windsurfbretter weisen demgegenüber zusätzlich zum Surfbrett ein Segel auf, das an seinem unteren Mastende gelenkig mit dem Surfbrett verbunden ist. Der Windsurfer kann so das Surfbrett nutzen, auch wenn kein Wellengang herrscht, aber dennoch Wind vorhanden ist.Surfboards have the disadvantage that without the advance of the wave, a pursuit of water sports is not possible. Windsurfing boards have in contrast to the surfboard on a sail, which is connected at its lower end of the mast hinged to the surfboard. The windsurfer can thus use the surfboard, even if there is no waves, but there is still wind.

Es sind aus der DE 20 2011 051 071.9 , die als nächstliegender Stand der Technik angesehen wird, Surfbrettanordnungen bekannt, die einen in einem Surfbrett integrierten Jetantrieb aufweisen, wobei der Jetantrieb über eine integrierte Steuerung, die der Surfer in seiner Hand halten kann, steuerbar ist. Die integrierte Steuerung ist sowohl für die Geschwindigkeit als auch für die Rechts-/Linkskurvenfahrt ausgelegt.They are from the DE 20 2011 051 071.9 As the closest prior art, surfboard assemblies are known which have a jet propulsion integrated in a surfboard, the propulsion of the jet being controllable via an integrated control which the surfer can hold in his hand. The integrated control is designed for both speed and right / left cornering.

Ausgehend von dem letztgenannten Stand der Technik, ist es Aufgabe der vorliegenden Erfindung, ein Surfbrett zur Verfügung zu stellen, das einen weiter erhöhten Fahrspaß ermöglicht.Based on the latter prior art, it is an object of the present invention to provide a surfboard available, which allows a further increased driving pleasure.

Die Aufgabe wird durch eine eingangs genannte steuerbare Surfbrettanordnung mit den Merkmalen des Anspruchs 1 gelöst, bevorzugte Ausführungsformen sind Gegenstand der Unteransprüche.The object is achieved by an aforementioned controllable surfboard arrangement with the features of claim 1, preferred embodiments are the subject of the dependent claims.

Die erfindungsgemäße steuerbare Surfbrettanordnung weist ein ein Heck und einen Bug aufweisendes Surfbrett mit einer Standfläche für einen Surfer und mit einer vom Heck zum Bug ausgerichteten Längsache auf. Die Anordnung umfasst einen Antrieb mit einer in einer Schwenkebene entlang der Standfläche verschwenkbaren Rückstoßeinrichtung zur Erzeugung von Links- und Rechtskurvenfahrten der Surfbrettanordnung und einem Vortrieb mit wenigstens einem im Surfbrett integrierten, Verkippungen im und entgegen dem Uhrzeigersinn um die Längsachse detektierenden Beschleunigungssensor und/oder Lagesensor, der die Schwenkrichtung der Düse derart steuert, dass eine Verkippung des Surfbretts entgegen dem Uhrzeigersinn um die Längsache die Düse in der Schwenkebene nach links schwenkt und im Betrieb eine Linkskurvenfahrt der Surfbrettanordnung bewirkt und eine Verkippung des Surfbretts im Uhrzeigersinn um die Längsache die Düse in der Schwenkebene nach rechts schwenkt und im Betrieb eine Rechtskurvenfahrt der Surfbrettanordnung bewirkt und mit einer Handsteuerung, mit der die Fahrtgeschwindigkeit steuerbar ist.The controllable surfboard arrangement according to the invention has a surfboard having a stern and a bow with a stand for a surfer and with a longitudinal axis oriented from the rear to the bow. The arrangement comprises a drive with a recoil device which can be pivoted in a pivoting plane along the standing surface for generating left and right turns of the surfboard arrangement and a propulsion with at least one acceleration sensor and / or position sensor in the counterclockwise and counterclockwise around the longitudinal axis detecting tilting with at least one integrated in the surfboard controls the pivoting direction of the nozzle such that tilting of the surfboard counterclockwise about the Längsache the nozzle in the pivoting plane pivots to the left and in operation causes a left turn of the surfboard arrangement and a tilt of the surfboard clockwise about the Längsache the nozzle in the pivoting plane pivots to the right and in operation causes a right turn of the surfboard arrangement and with a manual control, with the speed of travel is controllable.

Die Erfindung macht von der Idee Gebrauch, die Fahrtgeschwindigkeit und Kurvensteuerungen voneinander räumlich und bedienungsmäßig zu trennen. Zum einen steuert der Surfer die Kurvenfahrt durch Belastungswechsel auf dem Surfbrett, wohingegen der die Geschwindigkeit bestimmende Vortrieb mittels einer Handsteuerung erfolgt. Durch die Trennung der Kurven und Geschwindigkeitssteuerung wird der Fahrspaß erhöht.The invention makes use of the idea to separate the travel speed and curve controls from each other spatially and in terms of operation. On the one hand, the surfer controls the cornering by load changes on the surfboard, whereas the speed-determining propulsion is done by means of a hand control. By separating the curves and speed control the driving pleasure is increased.

In einer bevorzugten Ausführungsform der Erfindung umfasst der Antrieb einen Jetantrieb mit einer als Düse ausgebildeten Rückstoßeinrichtung. Düsen sind vorteilhafterweise besonders wartungsarm.In a preferred embodiment of the invention, the drive comprises a jet drive with a recoil device designed as a nozzle. Nozzles are advantageously particularly low maintenance.

Dabei sind vorzugsweise an einer Unterwasserfläche des Surfbrettes ein Wassereinlass und die Düse an einer Überwasserfläche zum Wasserausstoß angeordnet. Jetantriebe sind bewährte Antriebe für Wassersportgeräte. Sie sind günstigerweise auch in ufer- bzw. küstennahen und sehr flachen Gewässern verwendbar.In this case, preferably a water inlet and the nozzle are arranged on an underwater surface for discharging water on an underwater surface of the surfboard. Jet drives are proven drives for water sports equipment. They are also conveniently used in shore or coastal and very shallow waters.

In einer weiteren bevorzugten Ausführungsform der Erfindung ist der wenigstens eine im Surfbrett integrierte Sensor als Beschleunigungssensor und Lagesensor ausgebildet Besonders bevorzugt ist jeweils wenigstens ein Beschleunigungssensor und Lagesensor in einem Surfbrettkörper in einem backbordseitigen Bereich und einem steuerbordseitigen Bereich angeordnet. Der wenigstens eine Sensor kann mit einer Steuerung eines Stellmotors einer Schwenkachse der Düse in Verbindung stehen. Der Sensor dient vorzugsweise ausschließlich der Richtungssteuerung der Surfbrettanordnung durch Gewichtsverlagerung des Surfers auf der Standfläche. Sensoren zur Steuerung des Stellantriebs sind im Surfbrettkörper geschützt integriert eingebaut. Sie haben auch im Betrieb keinen Wasserkontakt.In a further preferred embodiment of the invention, the at least one sensor integrated in the surfboard is designed as an acceleration sensor and position sensor. Particularly preferably, at least one acceleration sensor and position sensor each are arranged in a surfboard body in a port side region and a starboard side region. The at least one sensor may be in communication with a controller of a servomotor of a pivot axis of the nozzle. The sensor is preferably used exclusively to control the direction of the surfboard arrangement by shifting the weight of the surfer on the floor space. Sensors for controlling the actuator are built-in integrated integrated in the surfboard body. They also have no water contact during operation.

Daneben ist vorzugsweise die Handsteuerung für den Surfer ausschließlich zur Veränderung der Fahrtgeschwindigkeit vorgesehen. Die Handsteuerung kann als eine Druckknopfsteuerung, aber auch als Kippsteuerung oder als Joystick ausgebildet sein. Zweckmäßigerweise steht die Handsteuerung über eine Funkverbindung mit einer Steuerung eines elektrischen Antriebs eines Impellers in Verbindung. Dadurch sind keine störenden Kabelverbindungen außerhalb des Surfbrettes notwendig.In addition, the hand control for the surfer is preferably provided exclusively for changing the driving speed. The hand control can be designed as a push button control, but also as a tilt control or as a joystick. Conveniently, the hand control is connected via a radio link with a controller of an electric drive of an impeller in combination. As a result, no disturbing cable connections outside the surfboard are necessary.

Das Surfbrett weist vorzugsweise einen im Surfbrett angeordneten Akku auf, der sowohl den Stellantrieb als auch den Impellerantrieb mit Strom versorgt. Der Akku ist über ein herkömmliches Stromnetz aufladbar.The surfboard preferably has a battery located in the surfboard, which supplies both the actuator and the impeller drive with power. The battery is rechargeable via a conventional power grid.

The invention will be described with reference to an embodiment in three figures. Showing:

Fig. 3
Top view, partly as a section of the surfboard arrangement in FIG. 1 ,

Die Figuren 1, 2 und 3 sind nicht maßstabsgerecht.The FIGS. 1 . 2 and 3 are not to scale.

Figur 1 zeigt ein Surfbrett 1 mit einem auf dem Surfbrett 1 balancierenden Surfer 2 mit einer Handsteuerung 3 in seiner rechten Hand in Ausübung des Surfsportes. FIG. 1 shows a surfboard 1 with a balancing on the surfboard 1 surfer 2 with a hand control 3 in his right hand in pursuit of surfing.

Die Handsteuerung 3 ist hier als ein durch einen Finger des Surfers 2 betätigbaren Druckknopf ausgebildet, der einen Sender für durch den Druckknopf erzeugte Steuerdaten umfasst. Der Sender ist über eine Funkverbindung 4 mit einem im Inneren des Surfbretts 1 angeordneten Empfänger datenleitend verbunden. Der Empfänger leitet die empfangenen Daten an eine erste Steuerung 6 für einen ersten Elektromotor 7 eines im Heck des Surfbretts 1 angeordneten Impellers 8. Die Handsteuerung 3 gestattet es, die Geschwindigkeit des Surfbretts 1 durch Verändern der Stellung des Druckknopfes zu steuern. Die Handsteuerung 3 kann auch als Joystick oder auch als ein handelsübliches Smartphone ausgebildet sein, das durch Verschwenken nach vorne in Fahrtrichtung bzw. nach hinten zum Surfer 2 eine Geschwindigkeitserhöhung bzw. -verminderung gestatten kann.The hand control 3 is here designed as a pushbutton which can be actuated by a finger of the surfer 2 and which comprises a transmitter for control data generated by the pushbutton. The transmitter is connected in a data-conducting manner via a radio link 4 to a receiver arranged in the interior of the surfboard 1. The receiver routes the received data to a first controller 6 for a first electric motor 7 of an impeller 8 located in the aft of the surfboard 1. The hand controller 3 makes it possible to control the speed of the surfboard 1 by changing the position of the push button. The hand control 3 can also be designed as a joystick or as a commercially available smartphone, which can allow an increase or decrease in speed by pivoting forward in the direction of travel or back to the surfer 2.

Der Impeller 8 ist Teil eines Jetantriebs, der einen an der Unterwasseroberfläche des Surfbretts 1 angeordneten Wassereinlass 9 aufweist. Der Wassereinlass 9 führt entlang eines Wasserkanals 11 zur am Heck des Surfbretts 1 angeordneten, in einer parallel zur Standfläche 13 des Surfbretts 1 verschwenkbaren Düse 12. Im Wasserkanal 11 ist der Impeller 8 angeordnet, der elektrisch durch den ersten Elektromotor 7 mittels einer Welle angetrieben ist.The impeller 8 is part of a jet propulsion system which has a water inlet 9 arranged on the underwater surface of the surfboard 1. The water inlet 9 leads along a water channel 11 to the rear of the surfboard 1 arranged in a parallel to the base 13 of the surfboard 1 pivotable nozzle 12. In the water channel 11 of the impeller 8 is arranged, which is electrically driven by the first electric motor 7 by means of a shaft ,

Der Elektromotor 7 wird über einen im Surfbrett 1 integrierten Akku 16 mit Strom versorgt. Der Akku 16 ist über einen üblichen Netzanschluss aufladbar. Derselbe Akku 16 versorgt darüber hinaus auch einen Stellantrieb 14 mit Strom, der im Heck des Surfbretts 1 vorgesehen ist. Der Stellantrieb 14 dient zum Verschwenken der Düse 12. Die Schwenkebene der Düse ist im Wesentlichen entlang, vorzugsweise parallel zur Standfläche 13 des Surfbretts 1 vorgesehen. Durch Verschwenken der Düse 12 und der dadurch bewirkten Veränderung der Rückstoßrichtung des durch den Wasserkanal 11 angesogenen und aus der Düse 12 ausgestoßenen Wassers kann das Surfbrett 1 in eine Rechts-/Linkskurvenfahrt gesteuert werden. Der Stellantrieb 14 ist über eine zweite Steuerung 17, die ebenfalls im Inneren des Surfbretts 1 vorgesehen ist, steuerbar. Die zweite Steuerung wird mit Messdaten zweier im Randbereich angeordneter Beschleunigungs- und Lagesensoren 18 beaufschlagt, die eine Kippbewegung des in Fahrtrichtung entlang der Längsrichtung L fahrenden Surfbretts 1 im Uhrzeigersinn als auch entgegen dem Uhrzeigersinn detektieren.The electric motor 7 is powered by a built-in surfboard 1 battery 16 with power. The battery 16 is rechargeable via a standard power connector. The same battery 16 also supplies an actuator 14 with power, which is provided in the rear of the surfboard 1. The actuator 14 serves to pivot the nozzle 12. The pivot plane of the nozzle is provided substantially along, preferably parallel to the standing surface 13 of the surfboard 1. By pivoting the nozzle 12 and thereby causing change in the recoil direction of the sucked through the water channel 11 and ejected from the nozzle 12 water, the surfboard 1 can be controlled in a right / left turn. The actuator 14 is controllable via a second controller 17, which is also provided in the interior of the surfboard 1. The second control is subjected to measurement data of two acceleration and position sensors 18 arranged in the edge region, which detect a tilting movement of the surfboard 1 traveling in the direction of travel along the longitudinal direction L in the clockwise direction as well as in the counterclockwise direction.

Die zweite Steuerung 17 ist so ausgelegt, dass eine Kippbewegung in Fahrtrichtung entgegen dem Uhrzeigersinn die Düse 12, wie in Fig. 3 von oben betrachtet, im Uhrzeigersinn verschwenkt, so dass das Surfbrett 1 in eine Linkskurvenfahrt gesteuert wird, während umgekehrt eine Kippbewegung des Surfbretts 1 in Fahrtrichtung gesehen im Uhrzeigersinn zu einem Verschwenken der Düse 12, von oben betrachtet in Figur 3, entgegen dem Uhrzeigersinn führt und das Surfbrett 1 in eine Rechtskurvenfahrt gesteuert wird. Die Kurvenfahrt wird jedoch vorzugsweise ausschließlich über die durch Gewichtsverlagerung des Surfers 2 erfolgte Kippbewegung des Surfbretts 1 insgesamt um seine Längsachse L bewirkt. Die vollständige Trennung der zweiten Steuerung (17) für die Linkskurvenfahrt und Rechtskurvenfahrt von der ersten Steuerung (6) der Fahrtgeschwindigkeit erhöht das Fahrvergnügen gegenüber einer Kurvenfahrt und Fahrtgeschwindigkeit integrierenden Steuerung.The second controller 17 is designed so that a tilting movement in the direction of travel counterclockwise the nozzle 12, as in Fig. 3 viewed from above, pivoted clockwise, so that the surfboard 1 is controlled in a left turn, while conversely a tilting movement of the surfboard 1 seen in the direction of travel in a clockwise direction to a pivoting of the nozzle 12, viewed from above FIG. 3 , leads counterclockwise and the surfboard 1 is controlled in a right turn. However, the cornering is preferably effected exclusively via the tilting movement of the surfboard 1 caused by shifting the weight of the surfboard 2 as a whole about its longitudinal axis L. The complete separation of the second controller (17) for the left turn and right turn from the first control (6) of the travel speed increases the driving pleasure against cornering and cruise control integrating control.
