Water sports device
The invention relates to a water sports device comprising an inflatable body component ( 1 ) having a longitudinal direction (L) and inflatable arms ( 8 a, 8 b ) on a rear end, the arms being distanced from one another and orientated in the longitudinal direction (L), between which arms a receptacle ( 2 ) having an inner contour is formed, and comprising a drive component ( 7 ) having a tread surface ( 4 ) and an underwater surface ( 3 ), which drive component is formed with a complimentary contour ( 10 a, 10 b, 11 ) on two longitudinal sides ( 10 a, 10 b ) that are distanced from one another and which component can be inserted into the receptacle ( 2 ) from the rear end, wherein the inner contour and the complimentary outer contour ( 10 a, 10 b, 11 ) form a connection to one another and a position of the inserted drive component ( 7 ) in the receptacle ( 2 ) is secured in the direction of the tread surface.
1. A surf board, comprising:
an inflatable hull component ( 1 ) having a longitudinal direction (L) and, at a stern end, inflatable arms ( 8 a , 8 b ) which are spaced apart from one another and which are oriented in the longitudinal direction (L), said arms forming therebetween a receptacle ( 2 ) having an inner contour, and
a drive component ( 7 ) having a tread surface ( 4 ) and an underwater surface ( 3 ) whereby the tread surface of the drive component ( 7 ) is flush with a tread surface of the inflated hull component ( 1 ), so that a common total tread surface is formed by the hull component ( 1 ) and the drive component ( 7 ), which drive component is formed with a complementary contour ( 10 a , 10 b , 11 ) on two spaced-apart longitudinal sides ( 10 a , 10 b ) and can be inserted into the receptacle ( 2 ) from the stern end, wherein the inner contour and the complementary outer contour ( 10 a , 10 b , 11 ) form a connection with one another and a position of the inserted drive component ( 7 ) in the receptacle ( 2 ) is fixed in the direction of the tread surface ( 4 ) and the underwater surface ( 3 ) and laterally, and
at least one fastening means ( 12 a , 12 b , 13 a , 13 b ) for fastening the drive component ( 7 ) in the receptacle ( 2 ), which fastening means can be opened and closed, is provided at the stern end of the drive component ( 7 ) and of the arms ( 8 a , 8 b ) and prevents the drive component ( 7 ) from slipping out of the receptacle ( 2 ) at the stern end.
2. The surf board according to claim 1 , wherein the connection forms a form-fitting connection.
3. The surf board according to claim 1 , wherein the two arms ( 8 a , 8 b ) are convex on their mutually facing inner sides in a cross-section perpendicular to the longitudinal direction (L), and the drive component ( 7 ) is concave on the two spaced-apart longitudinal sides ( 10 a , 10 b ) so that the concave longitudinal sides ( 10 a , 10 b ) engage partially around the convex arms ( 8 a , 8 b ) with a form fit.
4. The surf board according to claim 1 , wherein the two arms ( 8 a , 8 b ) are convex on their mutually facing inner sides along the entire extension thereof in the longitudinal direction (L) in a cross-section perpendicular to the longitudinal direction (L).
5. The surf board according to claim 1 , wherein the two arms ( 8 a , 8 b ) are circular in cross-section.
6. The surf board according to claim 1 , wherein the longitudinal sides ( 10 a , 10 b ) engage around the arms ( 8 a , 8 b ) in cross-section over at least of the circumference.
7. The surf board according to claim 1 , wherein the drive component ( 7 ) comprises a jet drive and a rechargeable battery.
8. The surf board according to claim 7 , wherein the drive component ( 7 ) has at least two chambers ( 14 a , 14 b ) which can be separated from one another, and a separating plane runs transversely to the longitudinal direction (L), and the fastening element ( 12 a , 12 b , 13 a , 13 b ), upon being closed, exerts a force in the longitudinal direction (L) and presses the two chambers ( 14 a , 14 b ) against one another.
9. The surf board according to claim 1 , wherein in each case at least one fastening means ( 12 a , 12 b , 13 a , 13 b ) is arranged on each of the arms ( 8 a , 8 b ).
10. The surf board according to claim 9 , wherein the at least one fastening means comprises an elastic rubber strap ( 12 a , 12 b ) with a thickened end which is arranged on the longitudinal sides, and a fork ( 13 a , 13 b ) which is arranged on the drive component ( 7 ) and which can engage behind the thickened end.
