Abstract

System and methods are provided that relate to a drive arrangement for propelling a boat, in particular a kayak. In some embodiments, the drive arrangement can include an electric drive motor with a shaft and a receiving device for receiving the shaft. An arresting element can be provided for determining a first desired distance along the shaft between the receiving device and the drive motor.

First claim

The invention claimed is:

1. A drive arrangement for propelling a boat, comprising:
a drive motor with a shaft;
a receiving device for receiving the shaft and attachable to a boat;
a steering device having a first leg and a second leg, the steering device being slidably disposed on the shaft to rotate the shaft around its longitudinal axis in a first direction or a second direction; and
one or more steering elements, wherein the one or more steering elements are fitted to the first leg and the second leg of the steering device for pivoting the shaft around its longitudinal axis through activating one of the one or more steering elements for steering the boat.

2. The drive arrangement according to claim 1 , wherein the first leg is connected to the second leg to define an opening for receiving the shaft therethrough for coupling the steering device to the shaft.

3. The drive arrangement according to claim 1 , further comprising an arresting element defining a receptacle for receiving the shaft, the arresting element being displaceable relative to the receiving device along a longitudinal axis of the shaft received in the receptacle to determine a first desired distance along the shaft between the receiving device and the drive motor.

4. The drive arrangement according to claim 3 , wherein the arresting element can be shifted into an opened position and into a closed position, wherein the arresting element can be displaced along the longitudinal axis of the shaft in the opened position and is fixed on the shaft in the closed position.

5. The drive arrangement according to claim 3 , wherein the arresting element is designed as a clamp with a quick-release lever, wherein the arresting element can be shifted into a closed position through tensioning the quick-release lever and into an opened position through loosening the quick-release lever.

6. The drive arrangement according to claim 1 , wherein the shaft is connected with the receiving device in such a way that the shaft can be rotated around a longitudinal axis of the shaft and the shaft can be displaced along the longitudinal axis of the shaft relative to the receiving device.

7. The drive arrangement according to claim 1 , wherein the steering device is arranged either above or below the receiving device and is in contact with the receiving device.

8. The drive arrangement according to claim 3 , further comprising a further arresting element that is arranged between the receiving device and the steering device, so that the receiving device and the steering device are at a distance from each other.

9. The drive arrangement according to claim 8 , wherein the further arresting element is arranged in such a way in a closed position that either the steering device or the receiving device lies on the further arresting element for blocking the steering device or the receiving device against a displacement along the longitudinal axis of the shaft.

10. The drive arrangement according to claim 1 , further comprising a connection device that is arranged at an upper end of the shaft for fixing a displacement of the shaft along the longitudinal axis of the shaft in a direction of the drive motor.

11. The drive arrangement according to claim 10 , wherein the connection device has a connection for connecting the drive motor to a power source.

12. The drive arrangement according to claim 1 , wherein the boat is a kayak.

13. A boat, comprising:
a drive arrangement comprising a drive motor with a shaft; a receiving device for receiving the shaft and attachable to a boat; a steering device having a first leg and a second leg, the steering device being slidably disposed on the shaft to rotate the shaft around its longitudinal axis in a first direction or a second direction for steering the boat; and one or more steering elements, wherein the one or more steering elements are fitted to the first leg and the second leg of the steering device for pivoting the shaft around its longitudinal axis through activating one of the one or more steering elements, for steering the boat.

14. The boat according to claim 13 , wherein the first leg being connected to the second leg to define an opening for receiving the shaft therethrough for coupling the steering device to the shaft.

15. The boat according to claim 13 , further comprising an arresting element defining a receptacle for receiving the shaft, the arresting element being displaceable relative to the receiving device along a longitudinal axis of the shaft received in the receptacle to determine a first desired distance along the shaft between the receiving device and the drive motor.

16. The drive arrangement according to claim 1 , wherein the one or more steering elements comprise at least two steering elements, wherein the at least two steering elements are fitted to the first leg and the second leg of the steering device for pivoting the shaft around its longitudinal axis through activating one of the at least two steering elements for steering the boat.

17. The boat according to claim 13 , wherein the one or more steering elements comprise at least two steering elements, wherein the at least two steering elements are fitted to the first leg and the second leg of the steering device for pivoting the shaft around its longitudinal axis through activating one of the at least two steering elements, for steering the boat.
