Surfboard having tilt control
The invention relates to a surfboard assembly that can be controlled, comprising a surfboard ( 1 ), which has a stern and a bow and which has a standing surface for a surfer ( 2 ), a longitudinal axis (L) oriented from the stern to the bow, a drive having a thrust device, which thrust device can be pivoted in a pivoting plane along the standing surface ( 13 ), for producing left and right cornering of the surfboard assembly, and a propulsion unit, at least one sensor ( 18 ), which is integrated in the surfboard ( 1 ) and detects tilting clockwise and counterclockwise about the longitudinal axis (L) and which controls the pivoting direction of the nozzle ( 12 ) in such a way that tilting of the surfboard ( 1 ) counterclockwise about the longitudinal axis (L) pivots the nozzle ( 12 ) to the left in the pivoting plane.
1. Controllable surfboard arrangement with
a surfboard ( 1 ) having a stern and a bow, with a standing surface for a surfer ( 2 ) and with a longitudinal axis (L) oriented from the stern to the bow, and
with a drive with a reaction propulsion device which can be swivelled in a swivel plane along the standing surface ( 13 ) to generate left and right turn movements of the surfboard arrangement, and a propulsion device,
with at least one sensor ( 18 ) integrated in the surfboard ( 1 ) and detecting clockwise and counterclockwise tilting about the longitudinal axis (L), which controls the swivel direction of the nozzle ( 12 ) such that a tilting of the surfboard ( 1 ) counterclockwise about the longitudinal axis (L) swivels the nozzle ( 12 ) to the left in the swivel plane and in operation causes a left turn of the surfboard arrangement, and a tilting of the surfboard ( 1 ) clockwise about the longitudinal axis (L) swivels the nozzle ( 12 ) to the right in the swivel plane and in operation causes a right turn of the surfboard arrangement, and
with a hand control ( 3 ) with which the travel speed can be controlled.
2. Controllable surfboard arrangement according to claim 1 ,
characterised in that the drive comprises a jet drive with a reaction propulsion device configured as a nozzle ( 12 ).
3. Controllable surfboard arrangement according to claim 2 , characterised by a water inlet ( 9 ) arranged on an underwater face of the surfboard ( 1 ) and a water expulsion nozzle ( 12 ) arranged on an overwater face.
4. Controllable surfboard arrangement according to claim 1 , characterised in that the at least one sensor integrated in the surf board ( 1 ) is configured as an acceleration and position sensor ( 18 ).
5. Controllable surfboard arrangement according to claim 4 , characterised in that the at least one acceleration and position sensor ( 18 ) is arranged in a surfboard body in a port-side region and in a starboard-side region.
6. Controllable surfboard arrangement according to claim 1 , characterised by a hand control ( 3 ) for the surfer ( 2 ), with which only the travel speed can be controlled.
7. Controllable surfboard arrangement according to claim 1 , characterised in that the hand control ( 3 ) is connected via a radio connection ( 4 ) to a first control unit ( 6 ) of an electric drive ( 7 ) of an impeller ( 8 ).
8. Controllable surfboard arrangement according to claim 1 , characterised in that the at least one sensor ( 18 ) is connected to a second control unit ( 17 ) of a servomotor ( 14 ) of a swivel axis of the nozzle ( 12 ).
